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.
