Determine importance of backwaters to native fish. <br /> <br />6. Develop criteria for self sustaining populations of humpback chub. <br /> <br />7. Monitor harvested and field sampled rainbow trout to determine the contribution of <br />naturally reproduced fish to the population. <br /> <br />8. Determine impacts of dam operations on trout habitat and redds. <br /> <br />9. Define areas and conditions of current and future existing and potential interactions <br />between native and non-native species. <br /> <br />10. Define current and historic food base character and structure. <br /> <br />11. Design and test an experimental program of steady flows to verify an effective flow <br />regime and quantify, to the extent possible, effects on endangered and native fish. <br /> <br />Riparian And Terrestrial Vegetation Resources <br /> <br />1. Determine historic natural composition of riparian and upland communities. <br /> <br />2. Characterize normal range of variation and ecology of species. <br /> <br />3. Monitor impacts of dam operating criteria on the successional processes of natural <br />vegetation communities. <br /> <br />4. Evaluate impacts of dam operations on establishment of and impacts from exotic plant <br />species. <br /> <br />5. Evaluate impacts of alternate dam operating criteria on vegetation communities. <br /> <br />6. Determine historic and current distributions, range of variation and ecology of T &E <br />and special status species. <br /> <br />7. Establish ecosystem requirements of special status species and determine probable <br />impacts of proposed flow regimes. <br /> <br />8. Monitor population changes in special status species. <br /> <br />Final Draft - (12/15/97) For AMWG Review <br />
