On the other hand, large releases modeled to meet the NPS desired peak flows would result in recommended fish peak flows being met more frequently at the Whitewater gage because of the large volume of water needed for the NPS peaks. Operating to meet NPS desired peaks met at least 90 percent of the endangered fish peaks about 60 percent of the time. The following table compares model runs to meet both the NPS desired flows and the endangered fish flow recommendations. Endangered Fish Flow Recommendations and NPS Desired Flow Comparison 90% of the NPS Peak 4% 19% 50% Met 90% of Endangered Fish 19% 58% 62% Peaks Met 100% of Required Flow 81% 38% 100% 90% of Required Flow 89% 65% 100% 80% of Required Flow 96% 77% 100% >95% of Desired Base 90% 97% 89% Flow >80% of Desired Base 96% 99% 94% Flow Occurrences when Base 87% 93% 84% Flow Demand> 1000 cfs *Provides a May peak with the same limitations as FWS Run C. It should be noted that operating to meet the desired tlows for both the NPS and the endangered fish will have significant negative effects on other resources. For example, operating to meet the NPS desired hydro graph will impact hydrpower, downstream fisheries and flooding at Delta, while operating to meet endangered fish flow recommendations will have greater impacts on resources dependent on reservoir levels such as the State of Colorado Compact entitlement, reservoir fisheries, and recreation. 15
