San Juan Basin Recovery Implementation Program Hydrology Model (2016-Ongoing)

Precision works with the Western Colorado Area Office of the Bureau of Reclamation, and other stakeholders of the San Juan Basin Recovery Implementation Program, to continue development and application of a daily timestep RiverWare® model of the San Juan River in southwestern Colorado and northwestern New Mexico. The model simulates detailed concurrent recovery program and water supply operations in Navajo Reservoir and downstream to Lake Powell, including coordinated operations on the Animas River and other important tributaries. The model is used for various planning type studies in the basin, including evaluation and revision of the 1999 SJBRIP Flow Recommendations and ESA Section 7 consultations of proposed actions within the basin.

See the San Juan Recovery Implementation Program Climate Change Study project for an example of how this model has been used.
