Wyoming Weather Modification Program: Projects

Siting and Design

Wyoming Range

The Wyoming Range, Phase II Feasibility Study was completed to assess the feasibility of increasing snowpack in the Wyoming Range that would ultimately melt and run off into western portions of the Upper Green River Basin (UGRB). The UGRB is an area of known water shortages as identified in the Wyoming Water Development Commission's (WWDC) Green River Basin Plan.

The study concluded that an operational cloud seeding program would be feasible to target the eastern slope of the Wyoming Range with streamflow increases into the UGRB. The basis for this conclusion came from the results of the climatological analysis, model evaluations, and benefit/cost estimates. The overarching results of the study indicate that the existing Idaho Power Company weather modification program is already effectively enhancing precipitation in the UGRB, and that further enhancement could be achieved by judicious placement of additional ground-based generators, and/or airborne seeding.

The Wyoming Range, Phase II Feasibility Study was deemed complete by the WWDC at the August 26, 2016 summer meeting.
