Montana Cancels Tongue River Reservoir Call
21 May, 2015

On April 10, 2015, 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 21, 2015, 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. 
Pilot System Water Conservation Program RFP Released
11 May, 2015
The Upper Colorado River Commission (UCRC) issued today a Request for Proposals (RFP) for the Pilot System Water Conservation Program for the Upper Colorado River Basin. Facing declining levels in Lakes Powell and Mead, the U.S. Bureau of Reclamation, and four major water providers that depend on the Colorado River Basin supplies have committed $11 million, of which at least $2.75 million is intended 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. Importantly, this two year pilot program is seeking proposals for conservation opportunities that would be voluntary, compensated, and temporary in nature.
A copy of the RFP and the application form are linked below. 

For questions, please contact Steve Wolff, Colorado River Coordinator, at or (307) 777-1942. 


State Engineer Orders Corrective Control in the Laramie County Control Area

Responding to mounting concerns over increasing development and use of groundwater resources in the Laramie County
Control Area (LCCA), State Engineer Pat Tyrrell issued an order on April 1, 2015 that will guide groundwater development
in that area for at least the next five years. 

The mission of the Wyoming State Engineer's Office and Board of Control is to provide for the general supervision and protection of both inter- and intra-state waters of Wyoming. This includes the appropriation, distribution and application to beneficial use of water as provided under the prior appropriation doctrine, and to maintain the flexibility within that framework to meet the changing needs of the citizens of Wyoming. The State Engineer's Office collects, analyzes, maintains and provides water related information for ensuring the appropriate management and regulation of Wyoming's water resources.
