Colorado River Basin Planning and Decision Support (2020-Ongoing)

Precision is supporting the Central Utah Water Conservancy District (Central) and the Colorado River Authority of Utah (CRAU) in planning and decision support on current and future Colorado River Basin policy decisions impacting the state of Utah. Central to this are the Colorado River Basin RiverWare© basin-wide models updated and maintained by the Bureau of Reclamation: the Colorado River Simulation System (CRSS) and the Colorado River Mid-term Modeling System (CRMMS). Precision uses CRSS and CRMMS to answer key planning questions for Central amid the current and future basin-wide considerations of hydrology, demand, and operational policy. Recent work has focused on Drought Response Operation Agreement (DROA) and Supplemental Environmental Impact Statement (SEIS) modifications to the 2007 Interim Guidelines (IG) as well as Post-2026 Colorado River Basin policy. Precision has developed comparison tools to evaluate basin policy across a wide range of hydrology and demand scenarios to help answer a wide range of questions and provide technical analysis in support of those questions.
