Wyoming State Water Plan

The Wyoming River Basin Plans, funded by the Wyoming Legislature beginning in 1997, quantify existing water uses and project future needs of this important resource. With the State divided into seven major drainage basins (Bear, Green, Platte, Northeast, Powder/Tongue, Snake/Salt, and Wind/Bighorn), individual plans are generated and regularly updated to assess current water use in different sectors and to identify and prioritize water development opportunities. These plans are designed to assist Wyoming municipalities, irrigation districts, and other public entities' efforts to plan for the future.


Develop essential information concerning the current status and future availability of water resources in Wyoming.


  • Maintain an inventory of accurate and contemporary water data for use by the Governor, State Legislature, state agencies, and the public.
  • Use the water data and information to facilitate successful Water Development Office planning projects and contribute to the Governor's Water Strategy.

2017 Wyoming Water Update meetings

The Wyoming Water Development Office invites you or any interested parties to attend the upcoming Wyoming Water Updates, hosted by the Wyoming Water Development Office. These meetings were once referred to as the Basin Advisory Group (BAG) meetings. We have a new name and a new mission! During these updates, you will hear about water issues and water projects as well as the water supply outlook for this coming water year. We will also update you on the latest information available from the River Basin Planning division.

See agendas here.
