Water Resource Modeling of the Colorado River: Present and Future Strategies

The CRSS is imprecisely configured to address water supply and environmental management issues within many large tributaries of the headwater branches, including the Colorado River upstream from Glenwood Springs, the Yampa River upstream from Maybell, the Little Snake River upstream from Lily, the Dolores River, the Duchesne River watershed, the White River upstream from Watson, the Animas River, the Little Colorado River watershed, the Virgin River watershed, and other tributaries in the Lower Basin. Today, river management programs, endangered fish recovery programs, and some Native American tribes are focusing on these tributaries. It is important for stakeholders to understand that the CRSS is most appropriate for addressing basin-wide issues but is not designed to address issues within these tributaries. Expanding the spatial resolution of the CRSS to do so will require significant effort.
