Our Recommendations

Our Recommendations

01

Maintain River Temperatures Below 65°F at Lees Ferry (River Mile 15)

Implement Seasonal Cool Mix Flows During Peak Summer Heat. Use of the dam's outlet works only during the hottest summer months, when surface warming threatens the trout fishery.

02

Use the Minimum Flow Necessary to Achieve the Temperature Target

Apply only the volume of cool-mix flow required to keep river temperatures below the critical threshold — no more than necessary.

03

Manage the Fishery Using Adaptive Science

Base operational decisions on ongoing temperature monitoring, biological surveys, and peer-reviewed research to refine and improve management over time.
