Wyoming Weather Modification Program: Projects


Wind River Range

With the completion of the field campaign portion of the Wyoming Weather Modification Pilot Program (WWMPP), ground-based seeding generators targeting the Wind River Range (WRR) were scheduled to be dismantled in the summer of 2014. However, due to interest expressed by several parties in continuing seeding operations in the target area for the winter of 2014-15, the generators were left in place and readied for the first-ever collaborative, operational weather modification program in the State of Wyoming.

Not only has cloud seeding been identified as a way to mitigate imbalances in water supply and demand in the Colorado River Basin (Colorado River Basin Water Supply and Demand Study 2012); but the implementation of operational weather modification programs is being considered as a long-term water management tool used to help ease the impacts of drought locally, and regionally.

Funding for operational cloud seeding in the WRR have been provided in part by the Wyoming State Legislature. Per the legislation, the appropriated funds can only be expended once formal cost-share agreements with interested parties are in place. This collaborative approach to funding cloud seeding operations in the WRR is anticipated to continue for future seasons. Cloud seeding operations in the Wind River Range have been funded in part by several Lower Colorado River Basin Entities (e.g. Central Arizona Water Project (CAP), Colorado River Board of California - Six Agency Committee (SAC), and Southern Nevada Water Authority (SNWA)).

Recently, several local companies have also become funding partners and made contributions toward the continuation of the program. The State of Wyoming is very appreciative of the support from following trona mining and energy companies, whom rely heavily on a health water supply in the Green River Basin: Genesis Alkalai, Solvay Chemicals, TATA Chemicals, Ciner Wyoming and Rocky Mountain Power.
