Summary Preliminary Opinion 

November 1, 2024  

LaPrele Irrigation District  

Board of Directors  

P.O. Box 115  

Douglas, WY 82633  

RE: LaPrele Dam Breach Order, Permit #1581R (Official Order here) 

Dear LaPrele Irrigation District:  

This letter serves as a Breach Order in response to the known structural deficiencies associated  with LaPrele Dam. The known structural deficiencies include but are not limited to:    

1. Shear cracks identified in the dam’s buttresses and the and former ogee spillway crest.  These cracks were discovered by HDR on September 24, 2019 and detailed in a technical  memo dated October 17, 2019. These deficiencies, primarily the cracking on Buttress  number 17, led to the implementation of a storage restriction dated November 20, 2019.  The storage restriction limited water storage to an elevation of 5475’. This also led to  additional investigations and analyses that identified further cracking in other buttresses  and locations in the dam.  

2. The movement of cracks on Buttress #2 and the former ogee crest of the dam. The  propagation of these cracks was first brought to the attention of the Wyoming State  Engineer’s Office (WYSEO) on August 16, 2024, and was further discussed with the  LaPrele Irrigation District (District) board members and their technical representatives  from HDR and RESPEC at a meeting on August 27, 2024.  

3. New cracking above the outlet pipe. A follow-up inspection was conducted by HDR on  October 14th and 15th, 2024 in response to the crack movement described above. That  inspection revealed new cracking located above the outlet pipe.  

Throughout the events described above, my office has been involved in discussions and meetings  with the District and its engineering consultant representatives as well as the Wyoming Water  Development Office. I appreciate this collaboration and the information the District has provided  throughout the multiple years we have been monitoring the LaPrele Dam conditions. This has  informed previous decisions including the 2019 fill restriction order issued by the WYSEO and  has been valuable as I make decisions necessary to fulfill my statutory responsibilities. On October  24, 2024, representatives from the WYSEO, the District, their technical representatives from HDR and RESPEC, and the Wyoming Water Development Office met and discussed the recent  indications of the dam’s deteriorating structural integrity, its inability to safely pass frequent hydrologic run-off flows, and the risks these conditions impose on life and property. Based upon  all of the information available, use of the dam to store water poses an unacceptable risk to life  and property. Due to the structural deficiencies listed above and the associated hydrological risk, my staff and I have determined that LaPrele Dam is an immediate threat to life and property as  described in Wyoming Statute § 41-3-314(a).  

It is therefore Ordered that the LaPrele Dam be fully breached (removed) to a final elevation  of 5400’ no later than April 1, 2025.  

Currently there is very little storage behind the dam and the outlet works are completely open and  under this Order shall remain completely open. The outlet is currently capable of passing the  inflows. Base flows during winter are not expected to exceed the dam’s ability to pass inflows and  will therefore not allow any new storage. The potential for any new storage to accrue is not  expected until after April 1, 2025 when inflows are expected to increase. However, because  hydrology is uncertain, if actual conditions indicate the potential for storage to occur, the WYSEO  may require the breach be completed prior to April 1, 2025.  

There are potential benefits to a higher elevation breach which are currently being discussed and  analyzed. At this time, sufficient information does not exist that a higher elevation breach can be  safely accomplished. Future amendments to this Order and the breach at elevation of 5400’ may  be considered if a clear benefit can be shown and it can be accomplished without an increased risk  to life and property.  

The Wyoming Safety of Dams Law requires that plans and specifications for any major repair or  rehabilitation that will affect the safety of the dam or the reservoir be prepared by a professional  engineer who is licensed in Wyoming. The plans and specifications are then to be submitted to the  WYSEO for review and approval prior to beginning any work. This requirement applies to any  work associated with the breach required by this Order.  

It is the District’s responsibility to comply with any other state or federal laws, regulations, or  permitting requirements which may apply to the breach required by this Order.  

Should you have any questions or comments regarding this matter please contact the WYSEO.  

Sincerely,  

Brandon Gebhart, P.E.  

State Engineer

Subject: Policy for Emergency Change in Place of Use for Stock Water (original memo linked)

     Date: May 31, 2024

With very dry conditions in some parts of Wyoming, I am authorizing emergency measures regarding changes in points of use for stock water only, extending through the calendar year 2024 only. This applies to surface water and groundwater sources. 

I will not require a formal permit or temporary water use agreement for appropriators to use stock water at points of use that are different than currently permitted. However, the following requirements must be met: 

The source must be a valid permit or adjudicated right with stock as a permitted use;

The use must be in priority in the source(s) of supply (no injury), and, if the source is a surface stream, it must not be declared to be in an "instream stock use only" condition. I am also delegating authority to each Division Superintendent to require that water be provided to meet reasonable demands for instream stock use for streams, as provided in W.S. 41-3-306, within their respective Divisions;

The change must be requested in writing to the Superintendent (you may make forms to keep these requests consistent); and

Permited rates of diversion shall not be exceeded. 

In short, the Superintendents may now authorize such changes in points of use with written documentation. If a request does not satisfy the above requirements, these simplified procedures cannot be used. 

Please contact me with any questions.

Subject: Policy on water for fire fighting (original memo linked)

     Date: May 31, 2024

With the potential for a dry season approaching in some parts of Wyoming, the State Engineer's Office may be contacted by various firefighting entities about our policy on the use of water for fighting wildfires. The occurrence of wildfires is usually unpredictable and finding water sources to fight wildfires is also unpredictable. Therefore, in emergency situations where wildfires are being managed, any water supply may be used for fighting the fire and any other ancillary uses such as dust abatement on roads, potable supplies, etc.

It is assumed that the entity in charge of fighting the fire will make an attempt to utilize the least disruptive water supply source available. If firefighting is occurring in your Division or District, any assistance you can provide in locating water supply sources for fighting wildfires will most likely be appreciated by the firefighting entity. It would be helpful if you keep a log of where water is obtained and an estimate of how much water is used.

      If you have questions regarding this Memorandum, please contact Jeff Cowley, 307-777-1942. 

The Laramie County Control Area Advisory Board will hold a special meeting on Monday, May 6, 2024 at 9:00 A.M. in Public Meeting Room 6 in the Capitol Extension (200 W 24th Street, Cheyenne, WY).

Subject: Policy on water for fire fighting (original memo linked)

     Date: July 25, 2023

With the potential for a dry season approaching in some parts of Wyoming, the State Engineer's Office may be contacted by various firefighting entities about our policy on the use of water for fighting wildfires. The occurrence of wildfires is usually unpredictable and finding water sources to fight wildfires is also unpredictable. Therefore, in emergency situations where wildfires are being managed, any water supply may be used for fighting the fire and any other ancillary uses such as dust abatement on roads, potable supplies, etc.

It is assumed that the entity in charge of fighting the fire will make an attempt to utilize the least disruptive water supply source available. If firefighting is occurring in your Division or District, any assistance you can provide in locating water supply sources for fighting wildfires will most likely be appreciated by the firefighting entity. It would be helpful if you keep a log of where water is obtained and an estimate of how much water is used.

      If you have questions regarding this Memorandum, please contact Jeff Cowley, 307-777-1942. 

CHEYENNE, Wyo. – On July 10, 2023, the State Engineer issued an "Open Letter to Appropriators and Interested Parties in the Vicinity of the LaGrange Aquifer Subject Area as Defined in the State Engineer's Order of July 19, 2013" (below) in which he conveyed his decision to maintain the provisions of the First Amended Order of the State Engineer - Horse Creek Basin issued May 31, 2017, amending the Original Horse Creek Order.  

The Horse Creek Basin Amended Order was issued for the LaGrange Aquifer and surface water diversions from Horse Creek at and below the Brown and LaGrange diversion in southern Goshen County, Wyoming on May 31, 2017.  While no public hearing was held within three years of the First Amended Order due to the COVID-19 pandemic, the State Engineer's Office continued to collect data and information pursuant to the Order and review the effects of its operation.  

The Amended Order calls for closing of the area to further permitting of large capacity wells, and for the adjudication of currently unadjudicated groundwater permits.  Also, groundwater used for irrigation from the LaGrange Aquifer is limited to 45 acre-inches for the three-water-year period (2023 through 2025). Some flexibility within the three-year period is allowed.  All groundwater wells permitted for over 25 gallons per minute are required to have flow meters installed, and to report use annually.  While so limited, groundwater use is not subject to calls for regulation from surface water rights.

Surface water diversions and reservoirs are also required to have acceptable control and measurement capabilities.  Those diversions seeking to divert water during the winter are required to have acceptable control and measurement capabilities prior to diverting in the winter of 2013-2014, and any such diversions are required to be spread across the appropriate permitted (or adjudicated) acres up to the soil holding capacity only.  

Beginning November 16, 2022, the State Engineer reviewed the effects of the last three years of operation under the Order. A summary of that information was presented at the February 21, 2023 public hearing in LaGrange.  Comments from area water users relative to the Order’s corrective controls were accepted both at the hearing, and for 30 days following the hearing.  Those comments, in addition to information collected by the SEO, were used to determine whether or not the terms of the Amended Order shall continue to apply, whether a new order should be issued, or if the Amended Order should be terminated.

The State Engineer decided the terms of the existing Amended Order will continue in force, for consecutive three-year periods, until a new order is issued.  

The Amended Order may also be replaced by an operating agreement entered into by all parties subject to the Amended Order, and approved by the State Engineer as provided by Wyoming Statute W.S. §41-3-915(c).

The Amended Order is available below.

Today State Engineer Brandon Gebhart announced that priority water administration in the Tongue River Basin under the Yellowstone River Compact has been lifted. State Engineer Gebhart made the announcement after receiving a letter from the State of Montana indicating the call was being lifted due to the improved hydrologic conditions within the basin. With Tongue River Reservoir in Montana likely to fill, administration activity is no longer required in Wyoming.

Montana placed the initial call on April 1, 2022, when snowpack conditions in the Tongue River were below average, and forecasts predicted below average spring runoff exacerbated by poor soil moisture conditions. However, since April 1, 2022, major improvements have occurred, including increased snowpack of about 40% combined with improved soil moisture conditions and increased water storage in Tongue River Reservoir.

The priority administration largely applied to storage accruals of post-1950 storage rights in Wyoming reservoirs. Any water stored in those reservoirs is now available for its permitted use, and is no longer subject to a later release to satisfy a shortage in Tongue River Reservoir. Many other water users in the basin were impacted due to the inability to divert post-1950 water rights during the administration period.

The Yellowstone River Compact Commission Technical Advisory Committee (TAC) members, consisting of Wyoming, Montana, and United States Geological Survey employees, continues to explore options to improve forecasting methods within the Tongue River Basin. The TAC is dedicated to improving forecasting skill in order to better predict spring runoff and the need for interstate administration in any given year.    

While the call to fill Tongue River Reservoir has lifted, any priority administration for senior Wyoming water rights is still in effect and many of the area rivers are likely to see normal stream regulation after the runoff period due to calls from senior appropriators. Montana still reserves the right to place a call in the future, if conditions warrant.

With very dry conditions in some parts of Wyoming, I am authorizing emergency measure regarding changes in points of use for stock water only, extending through the calendar year 2022 only. This applies to surface water and groundwater sources.

I will not require a formal permit or temporary water use agreement for appropriators to use stock water at points of use that are different than currently permitted. However, the following requirements must be met:

The source must be a valid permit or adjudicated right with stock as a permitted use;

The use must be in priority in the source(s) of supply (no injury), and, if the source is a surface stream, it must not be declared to be in an "instream stock use only" condition. I am delegating authority to each Division Superintendent to require that water be provided to meet reasonable demands for instream stock use for streams within their respective Divisions;

The change must be requested in writing to the Superintendent (you may make forms to keep these requests consistent); and

Permitted rates of diversion shall not be exceeded.

In short, the Superintendents may now authorize such changes in points of use with written documentation. If a request does not satisfy the above requirements, these simplified procedures cannot be used.

Today, Wyoming, along with the states of Colorado, New Mexico, and Utah, approved the 2022 Drought Response Operations Plan (2022 Plan). The 2022 Plan was developed to help reduce the risk that Lake Powell will decline below critical elevations. Protecting critical elevations at Lake Powell maintains hydropower generation and revenues, protects infrastructure, and helps maintain compliance with the 1922 Colorado River Compact, all of which benefit Wyoming. 

The Colorado River Basin is experiencing prolonged drought, low runoff conditions, and depleted storage in Lake Powell and Lake Mead. Recent studies indicate we are experiencing the driest conditions in the Basin in more than 1,200 years. Currently, Lake Powell is only 24% full, and the risk that it will fall below the critical elevation of 3,490 feet has continued to increase. 

The 2022 Plan was developed in accordance with the 2019 Drought Contingency Plans which were adopted to respond to ongoing drought and declining reservoir levels. It was developed through a collaborative process among the Department of the Interior and Upper Division States including Wyoming. Plan development included participation from Upper Basin Tribes and federal agencies, consultation with the States of Arizona, California and Nevada, as well as input from other Colorado River Basin Tribes, water users, stakeholders, and members of the public. Additionally, Wyoming received input from its Colorado River Working Group established by Governor Gordon to discuss Colorado River matters and their implications for Wyoming. 

The 2022 Plan includes the following elements: 

● Drought Response Operations releases of approximately 500,000 acre-feet from Flaming Gorge Reservoir from May of 2022 through April of 2023; 

● Possible Drought Response Operations releases from Blue Mesa Reservoir in Colorado and Navajo Reservoir in New Mexico in the fall of 2022 and winter of 2023, contingent upon available release 

volumes; and 

● Possible operational adjustments at Lake Powell in the winter of 2023. 

The 2022 Plan can be found on the Bureau of Reclamation’s website at https://www.usbr.gov/dcp/droa.html. 

Drought Response Operations releases from Flaming Gorge Reservoir were developed within the existing authorities which govern reservoir operations. Flaming Gorge is operated for authorized purposes, including helping the Upper Basin comply with the Colorado River Compact, water storage, contract

releases, power production, recreation, and environmental conditions downstream of the reservoir for endangered fish recovery. In addition to downstream flows, plan development considered Flaming Gorge Reservoir water levels and potential impacts to recreation. 

Implementation of the 2022 Plan will result in lower water elevations at Flaming Gorge Reservoir. Current projections indicate that the reservoir will drop to elevations similar to those experienced in the 2004 to 2005 timeframe. Depending on actual water inflows during the spring and summer, the reservoir will likely be approximately 6 feet lower than it is today by the end of August 2022, and approximately 10 feet lower than it is today by this time next year after the full 500,000 acre-feet has been released. 

The 2022 Plan has been forwarded to the Secretary of the Interior for her consideration and approval. If she approves the Plan, implementation will begin in May.

Wyoming State Engineer Brandon Gebhart announced yesterday that on April 1, 2022, the State of Montana placed a call under Article V(A) of the Yellowstone River Compact to fill Tongue River Reservoir in Montana. As a result, priority administration is in effect on post-1950 water rights in Wyoming which divert water from the Tongue River and its tributaries. 

The Tongue River Basin has been experiencing drought conditions over the past year with below average winter snowpack and streamflow conditions. These unfavorable conditions led to Montana’s interstate call, and prompted administration of the Tongue River Basin in Wyoming. 

The priority administration will affect post-1950 water rights within the Tongue River Basin, including storage in reservoirs, stream diversions, and groundwater withdrawals which affect river flows. As provided in the Compact, domestic uses less than ½ acre in area, and livestock uses, including stock reservoirs less than 20 acre-feet in capacity, are excluded from this administration but could be subject to future regulation to satisfy senior Wyoming water rights. All other post-1950 rights will be regulated off or prevented from turning on. Wyoming water commissioners will continue to administer reservoir storage and post-1950 diversions throughout the spring and work with affected water users until the administration is lifted. 

Beginning on April 1, Wyoming water commissioners have worked diligently to record current storage levels of reservoirs which have post-1950 water rights. Going forward, those reservoirs can continue to accrue storage with the understanding that post-1950 storage gained after April 1 must remain in storage until either the water is released to satisfy the Montana call or Montana lifts the call because Tongue River Reservoir will fill. Reservoirs that have unfulfilled pre-1950 water rights can also continue to store water, and that storage will not be subject to regulation due to Montana’s call. However, that storage could be subject to regulation to satisfy senior Wyoming water rights. 

The priority administration will be carried out pursuant to state law by the hydrographer/water commissioners assigned to various portions of the Tongue River basin, working under direction of Mr. David Schroeder, Division II Superintendent. 

A public meeting will be held on Tuesday April 26th from 4:30 to 6:30 located in the Inner Circle room at Sheridan County Public Library.

Wyoming State Engineer Brandon Gebhart announced today that, in accordance with Wyoming water law, priority administration is in effect on water rights diverting from the North Platte River and its tributaries upstream of and junior to Pathfinder Reservoir, priority of December 6, 1904; and between Pathfinder Dam and Guernsey Reservoir, priority of December 6, 1904, until such time as the administration is lifted, but no later than May 1, 2022. 

The North Platte River system has experienced multiple years of drought resulting in low reservoir storage carryover. Mr. Gebhart indicated the combination of previously below average snowpack conditions and low carryover storage in the U.S. Bureau of Reclamation reservoir system requires the administration of water rights junior to Pathfinder Reservoir. Based on the existing water supply, snowpack and forecasted runoff, it is anticipated that water supplies will be below average in 2022. 

The April storage and runoff forecasts for the coming season total 958,376 acre-feet and 946,066 acre-feet for the two river reaches subject to administration, well below the 1,100,000 acre-foot “trigger” value which represents a full North Platte Project ownership supply. Priority administration is required by Wyoming water law and is initiated by the request for regulation as provided by the Modified North Platte Decree to protect senior Wyoming water rights held by the U. S. Bureau of Reclamation for storage in its reservoirs. 

The immediate effects of the priority administration would mainly affect those junior priority water rights held by some municipalities and industries and storage reservoirs that may divert or store water. Letters have been sent to the municipalities and industries that may be affected by these administration activities. The letters inform the entities to review their water rights portfolio and determine if the water demand of their community will exceed their reliable water supply for the upcoming year. Alternatively, water may be obtained through temporary agreements or contracts from available storage, temporary change of use agreement, transfer or exchange agreement, or other supplies available under Wyoming law and approved by the Wyoming State Engineer’s Office. 

Since the initiation of the Modified North Platte Decree in 2001, and later the implementation of the Platte River Recovery Implementation Program (PRRIP), many of the municipalities located within the North Platte River basin have secured replacement water for their municipality in the event their existing rights cannot meet the water demand of the community. 

The priority administration actions for the affected water users will be carried out pursuant to state law by water commissioners assigned to various portions of the North Platte River basin. These State Engineer’s Office personnel will be in direct contact with the affected water appropriators and will also be available to assist water users with their questions. Even though regulation is only now formalized, some groups have been able to be forewarned of the upcoming administration. Follow up correspondence with affected users will happen as rapidly as possible. 

The State Engineer’s Office will continue to closely monitor the water supply conditions and will make adjustments to the administration actions warranted to reflect the changing situation.

Both the State Engineer, Greg Lanning, and Wyoming Governor's Representative on the Upper Colorado River Commission, Pat Tyrrell, have been keeping the Governor's office, Wyoming's Legislature, and stakeholders informed of the situation. Governor Gordon's office issued a press release on July 16, 2021 responding to the situation.

As the severe drought continues in the Colorado River Basin, the State of Wyoming will continue working closely with its own water users and stakeholders as well as the other Colorado River Basin States, the Bureau of Reclamation, and the Department of Interior.

With very dry conditions in some parts of Wyoming, I am authorizing emergency measure regarding changes in points of use for stock water only, extending through the calendar year 2021 only. This applies to surface water and groundwater sources.

I will not require a formal permit or temporary water use agreement for appropriators to use stock water at points of use that are different than currently permitted. However, the following requirements must be met:

The source must be a valid permit or adjudicated right with stock as a permitted use;

The use must be in priority in the source(s) of supply (no injury), and, if the source is a surface stream, it must be declared to be in an “instream stock use only” condition. I am delegating authority to each Division Superintendent to require that water be provided to meet reasonable demands for instream stock use for streams within their respective Divisions, even if no changes in points of use for stock water haven been requested;

The change must be requested in writing to the Superintendent (you may make forms to keep these requests consistent); and

Permitted rates of diversion shall not be exceeded.

In short, the Superintendents may now authorize such changes in points of use with written documentation. If a request does not satisfy the above requirements, these simplified procedures cannot be used.

State Engineer Greg Lanning will solicit comments on the 2015 Laramie County Control Area (LCCA) Order at a public hearing to be held March 4, 2020 in Room 108 of the Clay Pathfinder Building on the Laramie County Community College Campus from 1:00 P.M. to 4:00 P.M.

Responding to mounting concerns over increasing development and use of groundwater resources in the LCCA, former State Engineer Patrick Tyrrell issued an order on April 1, 2015 guiding groundwater development within the LCCA.

The 2015 Order identified four distinct areas within the LCCA characterized by varying hydrogeologic conditions and levels of development; the “Drawdown Area,” the “Conservation Area,” the “Unaffected Area,” and “Underlying Units.” In all but the “Unaffected Area,” which is largely north of Horse Creek, the order set forth well spacing requirements for all new wells.

The Order also requires meters for all wells except for stock and domestic uses, and metered amounts must be reported to the State Engineer’s Office annually. Meters had to be installed prior to use in Water Year 2017.

The State Engineer’s Office has been reviewing the effects of the Order since November 2019.

State Engineer Greg Lanning will solicit comments on the 2015 Order at the public hearing and for 30 days after the hearing. After receiving comments, the State Engineer will then determine whether or not the terms of the 2015 Order shall continue to apply or whether a new order should be issued. If no new order is issued by April 1, 2020, the terms of the 2015 Order will continue in force, for consecutive three year periods until a new order is issued.

The 2015 Order will remain effective until rescinded, superseded, or modified by another order of the State Engineer, or replaced by an appropriator agreement as envisioned in Wyoming Statute § 41-3-915(c) and approved by the State Engineer.

Summary of Comments 

In November, the Wyoming State Engineer’s Office, with the assistance of the University of Wyoming Extension, will be kicking off a public stakeholder process in the Green and Little Snake River Basins to investigate the feasibility of an Upper Basin Demand Management (DM) Program in Wyoming. The DM Program is one element of the Drought Contingency Plans (DCP) that were approved this past spring by the seven Colorado River Basin States and the Department of Interior.

The Colorado River Basin has been experiencing persistently dry hydrology since the turn of the 21st Century. Given these conditions, the Upper Division States of Colorado, New Mexico, Utah and Wyoming have coordinated with the Department of the Interior and stakeholders throughout the Basin to evaluate proactive options for protecting critical elevations at Lake Powell. Lake Powell is the Upper Basin’s primary storage facility to help assure continued compliance with the Colorado River and Upper Colorado River Basin Compacts, and the reservoir assists the continued use and development of Colorado River water by the Upper Division States.

The purpose of an Upper Basin DM program would be to support the voluntary, compensated, and temporary reduction of consumptive uses in the Upper Basin or augment supplies with imported water, if needed in times of drought, to help assure continued compliance with the 1922 Compact and without impairing existing water rights. Like mandatory curtailment, any DM program would be a state-based effort implemented under state law.

Within Wyoming, the water users of the basins involved must consider whether they want to see the state work to implement a DM program, and if they do, what that program should look like. In addition, no DM program can be created and implemented unless and until the four Upper Division States and the Upper Colorado River Commission determine it to be feasible and consistent with the terms of the DCP. If, after study, the States collectively agreed that a DM program is feasible, they may then develop and implement a program. A DM program may only be implemented if approved independently by each State’s Commissioner to the Upper Colorado River Commission and the Commission as a whole.

Dates and locations for upcoming public meetings to be held from 6-8 pm are as follows:

• Monday Nov. 4: Pinedale, Rendezvous Pointe Senior Center

• Tuesday Nov. 5: Green River, Sweetwater County Library

• Wednesday Nov. 6: Baggs, Little Snake River Conservation District Office

• Thursday Nov. 7: Cheyenne, Cheyenne Botanic Gardens, South Gathering Room

The seven Colorado River Basin States (including Wyoming), the Department of the Interior and water entitlement holders in the Lower Basin have been working diligently on a set of draft Drought Contingency Plan (DCP) agreements to respond to ongoing historic drought conditions and to reduce the likelihood of Colorado River reservoirs – particularly Lake Powell and Lake Mead – further declining to critical elevations.  Negotiations on the DCP agreements are nearing completion. The DCP agreements include an Upper Colorado River Basin DCP and a Lower Colorado River Basin DCP.  

The Upper Basin DCP is designed to: a) protect critical elevations at Lake Powell and help assure continued compliance with the 1922 Colorado River Compact, and b) authorize storage of water conserved in the Upper Basin that could help establish the foundation for a Demand Management Program that may be developed in the future.

The Lower Basin DCP is designed to: a) require Arizona, California and Nevada to contribute additional water to Lake Mead storage at predetermined elevations and, b) create new flexibility to incentivize additional voluntary conservation of water to be stored in Lake Mead. 

The Basin States seek to finalize the Upper and Lower Basin DCPs prior to the end of 2018 through the key DCP agreements identified below and federal legislation. 

Pat Tyrrell, Wyoming State Engineer, recently held several public meetings across the Green River Basin, as well as a publicly available webinar to inform the public about the current DCP efforts.  For those that were not able to participate in these events, but are still interested in the topic, there are two options linked below.  First, the presentation used during the public meetings is available to download at the link below.  In addition, a link to a recording of the webinar presentation is also available below.

The seven Colorado River Basin States (including Wyoming), the Department of the Interior and water entitlement holders in the Lower Basin have been working diligently on a set of draft Drought Contingency Plan (DCP) agreements to respond to ongoing historic drought conditions and to reduce the likelihood of Colorado River reservoirs – particularly Lake Powell and Lake Mead – further declining to critical elevations. Negotiations on the DCP agreements are nearing completion. The DCP agreements include an Upper Colorado River Basin DCP and a Lower Colorado River Basin DCP.

The Upper Basin DCP is designed to: a) protect critical elevations at Lake Powell and help assure continued compliance with the 1922 Colorado River Compact, and b) authorize storage of water conserved in the Upper Basin that could help establish the foundation for a Demand Management Program that may be developed in the future.

The Lower Basin DCP is designed to: a) require Arizona, California and Nevada to contribute additional water to Lake Mead storage at predetermined elevations and, b) create new flexibility to incentivize additional voluntary conservation of water to be stored in Lake Mead.

The Basin States seek to finalize the Upper and Lower Basin DCPs prior to the end of 2018 through the key DCP agreements identified below and federal legislation.

State Engineer Pat Tyrrell will be discussing drought contingency planning efforts in the Colorado River Basin at three upcoming public meetings. The Colorado River is now experiencing its 19 th year of drought. Since 2013, officials in the seven Colorado River Basin states, the Department of Interior and the Republic of Mexico have been working on drought contingency plans. Plans in the Lower Basin states of Arizona, California and Nevada have been developed separately, but parallel to, plans developed in the Upper Basin states of Colorado, New Mexico, Utah and Wyoming. Plans in both basins are now nearing completion.

The State Engineer will discuss the need for these plans, describe the contemplated plans, and answer questions at the three public meetings listed below.

Many permit applications request the beneficial use of Wyoming’s groundwater for miscellaneous uses that are considered by the State Engineer to be temporary in nature.  Upon approval, the permits are valid for a specified period of time and are termed “temporary” or “time-limited” permits.  These permits have an automatic cancellation date which is specified in the Additional Conditions and Limitations attached to the permit.  If an extension of time is not requested (and approved by the State Engineer) prior to the cancellation date, the permit is cancelled.   

Examples of temporary or time-limited uses authorized by permits include water supply wells for the oil and gas industry, mine dewatering, highway construction, gravel pits, and water hauling.

Adjudication of temporary or time-limited permits is not required. 

As the appropriator, it is your responsibility to know and understand the content of the conditions and limitations attached to your permit. 

If you have a temporary or time-limited permit and have questions regarding potentially extending the automatic cancellation date, please call the Ground Water Division at (307) 777-6163 before the cancellation date.  

At  their May 2018 meeting, the Board of Control adopted a policy extending the cutoff  date for new petitions from 30 days prior to the start of the meeting to 45 days prior.  This policy goes into effect for the November 2018 Board meeting.  The petition cut-off dates for the remainder of 2018 are as follows:

August 2018 Meeting - July 20, 2018

November 2018 Meeting - September 21, 2018

Download of Memo 

Since the early 1980s the State Engineer’s Office has required that stock watering wells applied for with a 25 gallons per minute (gpm) or less production rate be classified as a “miscellaneous -stockwatering pipeline” permit, which included a Beneficial Use (BU) Map upon adjudication, if the following conditions were met:

1. The application showed more than four (4) stock tanks, and/or

2. The application contemplated more than one mile of stock pipeline

By statute, such a “miscellaneous” use permit would then need to become adjudicated.  Frequently, appropriators complained about the cost of the BU map for adjudication, which required hiring a licensed surveyor or engineer.  If the typical 25 gpm stock well permit had less than 4 tanks, and less than a mile of distribution pipeline, neither adjudication nor a BU Map was required, and no certified survey was needed.

After significant review, the State Engineer has rescinded the previous policy and practice that required additional information, and higher cost, noting that a BU Map and adjudication will no longer be required for any single stock well proposing to use 25 gpm or less, regardless of the number of tanks or miles of conveyance (often by pipeline).  However, as a permit condition for those applications meeting the previous policy’s description of miscellaneous use, appropriators will still be required to provide the locations of their well and all points of use, but this information can be obtained using a hand-held Global Positioning System (GPS) device.  The primary requirement is that the well produce no more than 25 gpm at all times, a value the appropriator may be asked to verify during a field inspection. 

Similarly, the State Engineer has rescinded the previous policy and practice which limited domestic use filings to no more than one well per three single family dwellings. Once again, in addition to compliance with the Regulations and Instructions of the SEO relating to groundwater, the primary requirement is that flow from a single well produce no more than 25 gpm at all times or a miscellaneous filing will be required. Further, applications which propose to supply more than three single family dwellings with one well will be subject to the same permit condition described above for stock use.

Memorandom 

The Upper Colorado River Commission (UCRC) has issued another Request for Proposals (RFP) for the Pilot System Water Conservation Program for the Upper Colorado River Basin.  This RFP is for consideration of projects to be implemented in 2018.  Facing declining levels in Lakes Powell and Mead, the U.S. Bureau of Reclamation, and major water providers that depend on the Colorado River Basin supplies have made available money for use in the Upper Colorado River Basin to fund the Pilot System Water Conservation Program.  This program is designed to develop and test tools that could potentially be used as part of a drought contingency plan to help protect storage within the Colorado River basin.  This is the fourth round of proposals that the UCRC, funding partners and Wyoming State Engineer’s Office will consider.  All users of Colorado River water (Green and Little Snake River basins) are encouraged to consider developing a pilot project for consideration under this RFP.

For questions, please contact Charlie Ferrantelli (charlie.ferrantelli@wyo.gov; 307-777-6151) or Steve Wolff (steve.wolff@wyo.gov; 307-777-1942).

A special meeting has been set for the Wyoming State Board of Control, to commence on September 15, 2017, at 1:30 p.m., at the State Engineer’s Conference Room, 122 West 25th Street, Herschler Bldg. 1 West, Cheyenne, Wyoming. The agenda for this meeting is for the purpose of adopting Rules for Chapter 1, Fee Schedule, for the Wyoming State Engineer’s Office and Wyoming State Board of Control as a result of legislative changes in 2017.

If you have any questions, please contact Cheryl Timm, Wyoming State Board of Control, 1W, Herschler Building, Cheyenne, Wyoming 82002. 307-777-6899. cheryl.timm@wyo.gov.

Notice PDF 

The Wyoming State Engineer’s Office and the State Board of Control intend to promulgate rules to amend Chapter 1, “Fees”, of the State Engineer’s Office’s rules. In 2017, the Wyoming Legislature amended multiple statutes which shifted the responsibility for payment of water right adjudication advertisement fees from the County where the water right is located to the appropriator who holds the water right. Both the Statement of Principal Reasons and the proposed rules can be viewed and/or downloaded from the State Engineer’s Office website at http://seo.state.wy.us/, or the Secretary of State Website at https://rules.wyo.gov/. A copy of the proposed rules may also be obtained at the offices of the Wyoming State Board of Control, 122 West 25th Street, Herschler Building 1W, Cheyenne, WY 82002. If you have questions regarding the proposed rule changes, or to request a hard copy of any of the materials, please contact Nancy McCann at 307-777-5958.

The proposed rules will be open for public inspection and comment for at least 45 days, commencing on June 21, 2017, and ending on September 12, 2017. Any person may present their written comments on the proposed rules by emailing to seo.rules@wyo.gov. Any person may also send written comments on the proposed rules to the attention of Nancy McCann, Wyoming State Engineer’s Office, 122 West 25th Street, Herschler Building 1W, Cheyenne, Wyoming 82002. Written comments must be filed no later than September 12, 2017

Notice of Intent 

Proposed Rule Change Packet 

The Wyoming State Board of Control adopted Emergency Rules for Chapter 1, “Fees”, of the General Agency, Board or Commission Rules. The Emergency rules were implemented on July 13, 2017 and are in effect until November 10, 2017. The Board of Control will begin the regular rule making process to make the rule permanent. This Emergency rules process became necessary after legislative changes that amended multiple statutes became effective on July 1, 2017. The 2017 Wyo. Sess. Laws 241 (Ch. 99) shifted the responsibility for payment of water right adjudication advertisement fees from the County where the water right is located to the appropriator who holds the water right. The Emergency rules were adopted and implemented to reflect those statutory changes to allow for the collection of the appropriate fee from appropriators and to proceed with water right adjudications. “These emergency and, ultimately, permanent rules are required due to the passage of HB 47,” State Engineer Pat Tyrrell said. “Without them, we’d be non-compliant with the revised statutes and unable to accept advertising fees from the proper source.”

The adjudication cost of the Proof Fees for Surface Water Proofs and Ground Water proofs is now $70.00 for each proof. The proof fee covers the cost of recording the certificate in the county clerk's office and also pays for the cost of advertising.

Fee Schedule 

As of July 10, 2017, 4,100 acre-feet (AF) of Bear River Original Compact Storage (OCS) is available for allocation to Wyoming water users in the Bear River Basin. Facilities that receive a storage permit from the Wyoming State Engineer’s Office indicating they have been awarded OCS under the terms of the 1958 Compact are exempt from storage restrictions when the elevation of Bear Lake (located in Utah – Idaho) drops below a surface elevation of 5,911 feet. Appropriators who receive a storage right other than OCS may be regulated off when Bear Lake drops below elevation 5,911 feet.

At this time, it is the intent of the Wyoming State Engineer to allocate up to 1,100 AF of the remaining OCS water to small water users/projects (less than 100 AF) in the basin. The remaining 3,000 AF of OCS will be reserved for larger projects.

Criteria and documentation requirements for eligible water appropriators are outlined in the following policy memorandum. The deadline to submit requests for OCS allocation is September 30, 2017.

Following data collection and review, a public hearing, and receipt of public comment, State Engineer Pat Tyrrell issued an order today that will modify groundwater use limitations for the next three years in the LaGrange area.  The First Amended Order modifies the terms of an Order issued on July 19, 2013, in accordance with the terms of that previous Order.

More specifically, the order was issued for the LaGrange Aquifer and surface water diversions from Horse Creek at and below the Brown and LaGrange diversion in southern Goshen County, Wyoming. In crafting the First Amended Order, Tyrrell took into account groundwater and surface water use information gained in the first three years of operating under the original Order, as well as comments received from area water users, as expressed at a public hearing in LaGrange on February 15, 2017 and the 30-day comment period that followed. 

Notably, according to Tyrrell, groundwater production in the first three years under the original Order was significantly below the amount believed to be sustainable under the current level of knowledge.  Partly, this was due to favorable hydrology, and to modifications some operators made to their operations.  In the last three years there have been no calls for surface water regulation, and Hawk Springs Reservoir has filled every year. “Only about 48 percent of the allotted groundwater was pumped in the first three years.  So, we’ve underutilized the LaGrange Aquifer in some ways,” said Tyrrell.  “Those who would benefit from a larger cap should be able to do so, and we can do that, I believe, without jeopardizing the resource in the meantime.” 

In the order, Tyrrell continues the original Order’s closure of the area to further permitting of large capacity wells, and continued the requirement of the adjudication of currently unadjudicated groundwater permits prior to use.  However, the First Amended Order increases the allowable groundwater used for irrigation from the LaGrange Aquifer from 12 inches per year (36 inches for the 3-year period) in the original Order to a total of 45 inches for the next three water years (starting in water year 2017), with no more than 20 inches produced in any one year.  All groundwater wells permitted for over 25 gallons per minute will also be required to continue to have flow meters installed, and to report their use annually.  While so limited, groundwater use will not be vulnerable to calls for regulation from surface water rights. 

Surface water diversions, and reservoirs, will still be required to have acceptable control and measurement capabilities.  Similarly, those diversions seeking to divert water during the winter will be required to have acceptable control and measurement capabilities prior to diverting in the winter, and any such diversions will be required to be spread across the appropriate permitted (or adjudicated) acres up to the soil holding capacity only. 

The First Amended Order is in effect for a period of three years, (water years 2017-2019) after which these conjunctive management measures will be reassessed again. The current order continues to focus largely on water use data acquisition.  At that time, the current Order will either remain in effect or terminated, a new Order will be issued, or the Order will be replaced by an agreement among the affected appropriators.

When the Wyoming Water Development Commission and members of the Select Water Committee of the Wyoming Legislature raised questions related to our rights and abilities regarding the Colorado River in late 2015, it was fitting that this office step up and offer to create a document to address the issue of Wyoming’s role in the management of the Colorado River. That document can be found at the link below. It is my sincere hope that having this Law of the River summary, and its Wyoming effects, distilled down to essential components and hopefully written for a wide audience, will be helpful as these and other groups and individuals forge Wyoming’s future in the basin.

The intent of this Report is to inform its readers about the current issues on the river, Wyoming’s uses of the river, and to describe the varied laws, compacts, decrees, operating plans, and other instruments that have come to be as uses of the Colorado River Basin have matured and evolved since the early 1900s. It also discusses the effects of those instruments in and on Wyoming. What is our role as a Colorado River Basin State? What benefits do we get from the compacts on the river, and are we also constrained by them? Should we care about uses of water in Mexico? Should we care about the salinity of the water diverted at the All-American Canal in California? Might endangered fish in Utah affect water use in Wyoming?

Our hope is to delve into these important questions, and more, in a way that educates water managers, appropriators, our citizenry and governmental officials across the state. The Colorado is a complex river basin, often misunderstood and the subject of many an urban myth. In the coming pages, we hope you’ll learn more about this marvelous resource and Wyoming’s place at the table.

Wyoming and the Colorado River: A Report (2016) 

Information provided on completed U.W. 6 Forms, or "Statement of Completion and Description of Well or Spring" forms, allows the State Engineer's Office (SEO) to collect and maintain accurate details regarding the construction of water wells.  

In support of the Licensing Board's efforts to require licensed water well drilling contractors to submit the forms to the SEO, the State Engineer requested and received the advice and consent of the Board of Control to require such reports on November 18, 2015.  

Effective September 9, 2016, licensed water well drilling contractors are required to submit completed U.W. 6 Forms to the SEO within 90 days of well completion.  Wyoming Statute defines completion of a water well as "...when it is possible to install a pump and pump water.  In the case of an artesian well, completion is the time when the drill rig is moved off of the drilling site. 

Water Well Drillers Memo 

On April 19, 2016, the State of Montana made a call under the Yellowstone River Compact to fill Tongue River Reservoir. That call applied to Wyoming water rights with a priority date later than January 1, 1950. Since Montana made its call, the Wyoming State Engineer’s Office has communicated with Tongue River Basin water users, monitored water use in Wyoming, and curtailed water use by post-1950 water rights. On May 2, 2016, Montana cancelled its call. Accordingly, any water user in Wyoming’s Tongue River Basin may use water in accordance with the user’s water right until or unless otherwise regulated or notified by a Wyoming Water Hydrographer/Commissioner.

State Engineer Pat Tyrrell said that unlike last year when Montana cancelled the call after Tongue River Reservoir filled, Montana officials this year determined, under current snowpack and runoff conditions, that the reservoir will fill without continuing the call for regulation. “In that regard, I very much appreciate Montana’s proactive decision and their informing us so that Wyoming appropriators with post-compact rights wouldn’t be further curtailed under an interstate regulatory event. We are glad it appears Tongue River Reservoir will fill, which is beneficial to water users in both states.”

Governor Matt Mead has appointed David Schroeder as the new Water Division II Water Superintendent in Sheridan.  Schroeder, who worked for the State Engineer’s Office Water Division II from 2005 to 2014, replaces Carmine Loguidice, who retired March 8th with over 28 years service.  Schroeder will start April 11, 2016.

The Division II Superintendent is based in Sheridan, WY and oversees water administration in the Tongue River, the Belle Fourche, the Powder River, Cheyenne River and all tributaries within those drainages.

“Water Division II has unique challenges, for example operations under the Yellowstone River Compact following the litigation with Montana.  I look forward to David’s contributions in this matter and others,” Governor Mead said.

The Superintendent supervises water commissioners’ administration and regulation of waters and is a member of the constitutionally created State Board of Control, which is responsible for adjudicating and modifying Wyoming water rights.

State Engineer Patrick Tyrrell congratulated Schroeder on his appointment. “David played an important role in the highly visible MT v. WY lawsuit.  That experience I’m sure helped prepare him for what will be a very important role moving forward in Division II,” Tyrrell stated.  “He is well qualified and I welcome his contributions to Water Division II.”  Tyrrell asks that constituents in Water Division II who have water-related questions for this office contact Mr. Schroeder or his staff at the Sheridan office at 307-674-7012

Governor Matt Mead has selected three Wyoming citizens to serve in positions that support Wyoming’s participation in the management of the Colorado River.  The three are being named, in part, to fill positions that were previously held by Dan Budd, who passed away in September.

Mr. Randy Bolgiano and Mr. Keith Burron have been named as Alternate Wyoming Commissioners to the Upper Colorado River Commission (UCRC).  Where previously Wyoming had two Alternate Commissioners, there now will be three due to the rising importance to Wyoming of water supply and use issues in this basin.  The UCRC is an interstate, administrative agency established by the Upper Colorado River Basin Compact of 1948 (Upper Basin Compact).  UCRC members consist of a Commissioner representing each of the four Upper Division States of Colorado, New Mexico, Utah and Wyoming (Upper Division States) and a Commissioner appointed by the President of the United States who serves as the Chair of the Commission.  The Commission assists the Upper Division States in developing their apportionments of Colorado River water pursuant to the Colorado River Compact of 1922 and the Upper Basin Compact, and has specific responsibilities to assist in implementing the Upper Basin Compact consistent with laws of the Upper Division States.  Benjamin Bracken of Green River continues to serve in the third Alternate Commissioner position.

Mr. Bolgiano is a rancher from Boulder, Wyoming and has been active in the Green River Basin on water and other natural resource activities for more than two decades.  Mr. Burron is an attorney for Crowley Fleck in Cheyenne focusing predominantly on water rights, natural resources, public lands, water quality, oil and gas, and regulatory matters. Mr. Burron has been an active member of the Colorado River Water Users’ Association for almost 20 years years. The two will serve on the Commission along with Wyoming’s Commissioner, State Engineer Patrick Tyrrell, and Ben Bracken of Green River, also an Alternate Commissioner.

Governor Mead has also named Mr. Chad Espenscheid of Big Piney to serve as one of three Wyoming representatives on the Colorado River Basin Salinity Control Forum (Forum).  Mr. Espenscheid is a rancher and small business owner.  Created in 1973, the Forum is an organization of the seven Colorado River Basin states of Arizona, California, Colorado, Nevada, New Mexico, Utah and Wyoming.  The purposes of the Forum are to coordinate salinity control efforts among the states, coordinate with federal agencies on the implementation of the Colorado River Basin Salinity Control Program, work with Congress on the authorization and funding of the Program, act to disseminate information on salinity control and otherwise promote efforts to reduce the salt loading to the Colorado River.

“The Division Superintendent plays a vital role in water management. Kevin has served as the interim Superintendent since February – I believe Kevin will do a good job,” Governor Mead said.

The Division 4 Superintendent is based in Cokeville, WY and oversees water administration in the Snake River, the Bear River, the Green River and all tributaries within those drainages. 

The Superintendent supervises water commissioners’ administration and regulation of waters and is a member of the constitutionally created State Board of Control, which is responsible for adjudication of Wyoming water rights.

State Engineer Patrick Tyrrell congratulated Payne on his appointment. “Kevin’s service to the agency and our constituents has been outstanding and I look forward to working with him in his important new role,” Tyrrell stated.  “He is well qualified and I welcome his contributions to Water Division 4.”  Tyrrell asks that constituents in Water Division 4 who have water-related questions for this office contact Mr. Payne. You may continue to contact the Cokeville office at 307-279-3441.

On Friday, September 5, 2015 in Worland, District Court Judge Robert Skar signed the final documents related to the closing of the Big Horn General Adjudication lawsuit.  The three decrees signed include one on records retention, one closing the Phase III portion of the general adjudication, and the final overall Big Horn decree.  While appeals of various aspects of Friday’s actions may come forth, the final decree signals a close to some 37 years of litigation and adjudication efforts.

Phase I of the case dealt with the quantification of Tribal Awards on the Wind River Indian Reservation.  In total, those awards included approximately 290,000 acre-feet for presently or historically irrigated lands, and 209,000 acre-feet of “futures” awards for five identified but yet-to-be-constructed irrigation projects.  All Phase I awards were given a priority date of July 3, 1868, and comprise now the most senior rights in Division III.  With irrigated agriculture as the primary use for Tribal awards, the court also recognized subsumed uses including stock, domestic, municipal and commercial purposes.  Phase II of the case adjudicated other federal non-tribal rights, such as those used on national forests and BLM lands.  The Phase II reserved rights have priorities that range from dating back to the creation of the Shoshone and Big Horn National Forests to as recent as 1982-1983.  Phase III included adjudication of state water rights of various priorities that were unadjudicated as of 1984.  Included in Phase III was adjudication of over 4,600 surface water permits, including permit 7300 serving Midvale, Riverton Valley, and LeClair Irrigation Districts.  Permit 7300 is the single largest direct flow permit in the State of Wyoming.  In addition, Phase III also included numerous groundwater rights.

“The case took so long because of its sheer size,” noted State Engineer Pat Tyrrell.  “Between the three phases, the adjudication efforts needed for roughly a quarter of the state, and awaiting the outcome of seven Wyoming Supreme Court decisions, it simply couldn’t occur much quicker.  A similar general adjudication of the Snake River Basin in Idaho took about the same amount of time, and they are just finishing up too.”

Tyrrell also indicated that a number of positive things come from the process and the final decree.  “All state water rights in the Wind/Big Horn River system with priority dates of 1984 and earlier, if not adjudicated by that time, now are.  That’s a big deal.  This is the only water division in the state having gone through a full general adjudication, so its records have been largely cleaned up.  Likewise, the priority and quantity of all federal tribal and non-tribal rights are now known.  The uncertainty over what comprised these rights has been removed.”

Looking forward, the final decree means that adjudications formerly sent to the district court for interlocutory decisions will now revert to the more traditional Board of Control evaluation and adjudication.  Changes in existing rights and awards will also go before the Board.  In performing necessary administrative functions post-decree, the State Engineer’s Office will continue to manage water in cooperation with the office of the Tribal Water Engineer.

As many folks are learning, the State Engineer’s Office has developed an online permitting system called e-Permit. Now in its seventh year, this system allows appropriators to research water rights, but also allows them to submit applications as well as Statement of Completion (S.C.) Forms (Form U.W.6). Furthermore, e-Permit also provides a mechanism for water well contractors to submit S.C. Forms. The S.C. Form reports information regarding well construction to the State Engineer’s Office which is critical for our understanding of groundwater appropriations within Wyoming.

In general, e-Permit contains fields which are analogous to the fields on our paper forms; however, e-Permit requires certain fields to be filled in before accepting an electronic form.  These fields were identified early in development of e-Permit and were chosen based on historic recognition of the minimum basic information necessary to describe Ground Water rights within Wyoming.

The Ground Water Division (Division) still accepts paper forms and they continue to outpace electronic forms.  Over the past several years, the Division has accepted paper forms which do not necessarily contain all information which an e-Permit submittal requires. Instead, the Division preferred to contact appropriators to obtain the missing data.  Unfortunately, this data collection effort consumes time which should be devoted to processing the forms, and the data collection effort has created a two-year backlog for S.C. Form review.  This is especially unfair to those appropriators submitting complete forms.  All groundwater appropriators deserve a timely response to submittals and a timely review of S.C. Forms.

Consequently, the Division will no longer be accepting paper S.C. Forms which do not contain the minimum information required by the e-Permit system.  If the Division receives S.C. Forms which are not complete, they will be returned to the sender with a letter explaining the required fields.  This will result in a more streamlined process.  The Division appreciates everyone’s patience and understanding as we implement a process to streamline S.C. Form review.

Coal bed methane wells are wells drilled into a coal seam to capture and produce gas. The process includes pumping water to the surface to release the gas. As gas production subsides the wells are either reclaimed, or in some cases can be converted for use as a water source. Although coal bed methane wells are scattered throughout the state, the majority of wells are in northeast Wyoming.

As agency directors in charge of managing the State of Wyoming’s non-federal mineral and water resources, the Wyoming Oil and Gas Conservation Commission Supervisor Grant Black, and the State Engineer Patrick Tyrrell have written a guidance letter to explain the details of the proper conversion of coal bed methane wells for domestic and stock use. 

Landowners may be approached by CBM well operators with an offer to transfer well to the landowner and at the same time allowing release of the WOGCC bond on the well(s) and possibly the operator of the responsibility of plugging, abandoning and reclaiming the well. There are other cases where a landowner is interested in taking responsibility for an orphaned CBM well and converting it for use as a stock or domestic well. “These conversions, at their core, are something we support”, say Supervisor Black and State Engineer Tyrrell. “It makes use of an existing asset, can provide water for people and animals, and can have positive benefits for wildlife, including sage grouse”.

The questions become those of scope, process, and information. Questions for consideration include: How many wells should be converted in a defined area? What do the landowner and operator have to do with both our agencies to make sure the conversion is acceptable? What happens to the wellbore, and any associated liability, if turned over to a landowner and never recompleted or fully plugged and abandoned? Converting wells without analysis and proper approval will lead to potential liabilities for landowners and the potential risk that may be imposed upon mineral and groundwater resources.

The guidance letter will be posted on the web site of the two agencies. Links to both sites can be found on the State of Wyoming website. The guidance letter is two pages with an additional page as an attachment listing the steps and actions necessary to transfer a well.

Green Basin Water Users Meeting 

CHEYENNE, Wyo. - Responding to concerns over increasing conflicts between surface water and groundwater resources in southeast Wyoming, State Engineer Pat Tyrrell issued an order today that will limit groundwater use for the next three years in the LaGrange area while the area’s groundwater and surface water uses are re-appraised.

More specifically, the order was issued for the LaGrange Aquifer and surface water diversions from Horse Creek at and below the Brown and LaGrange diversion in southern Goshen County, Wyoming. In crafting the order, Tyrrell took into account concerns voiced by area water users, as expressed at a public hearing in LaGrange on April 12, 2013.

In the order, Tyrrell calls for closing of the area to further permitting of large capacity wells, and for the adjudication of currently unadjudicated groundwater permits. Also, groundwater used for irrigation from the LaGrange Aquifer will be limited to 12 inches per year for the next three years (starting in 2014), and a total of 36 inches over that period. Some flexibility within the 3-year period is allowed. All groundwater wells permitted for over 25 gallons per minute will also be required to have flow meters installed, and to report their use annually. While so limited, groundwater use will not be vulnerable to calls for regulation from surface water rights.

Surface water diversions, and reservoirs, will also be required to have acceptable control and measurement capabilities. Those diversions seeking to divert water during the winter will be required to have acceptable control and measurement capabilities prior to diverting in the winter of 2013-2014, and any such diversions will be required to be spread across the appropriate permitted (or adjudicated) acres up to the soil holding capacity only.

The Order is in effect for a period of three years, after which these conjunctive management measures will be reassessed. Therefore, the current order focuses largely on water use data acquisition. At that time, the current Order will either remain in effect or terminated, a new Order will be issued, or the Order will be replaced by an agreement among the affected appropriators. The order will be posted on the State Engineer’s website on Monday, July 22, 2013.

The State Engineer rescinded the January 4, 2005, "Policy Memo:  Permitting Requirements for Groundwater Monitoring Wells", effective March 12, 2013.  The Ground Water Division will no longer require permits for monitoring wells - regardless of the casing size.  The Water Well Minimum Construction Standards (Chapter 2, Section 2 (ww)), defines a monitoring well as, "A groundwater level observation well or a well from which water samples are retrieved for water chemistry analysis."  Therefore, there is no production of water for beneficial use and a monitoring well will not require a permit.
