<br />RESPONSE: The frequency of flows at 300 ft'/s would increase <br />significantly with the project, particularly in the nonirrigation <br />season. The EIS presents information on minimum and optimum flow <br />levels in the river; the development alternatives do not provide <br />optimum flOws. The existing conditions in the river have <br />developed over a wide range of flows; rarely have they been or <br />stayed in the 500- to 600-ft'/s range. The EIS evaluates the <br />difference between the no-action flows and the with development <br />flows, none of which represent optimum conditions. <br /> <br />Low flows in the Uncompahgre through Montrose would reduce the <br />potential for a fisheries development in this reach. Additional <br />information has been developed for the EIS on this subject; also <br />see RESPONSE to C~ OR-21. Fishery conditions should improve <br />upstream from the Loutzenhizer Diversion Dam and downstream from <br />the tailrace. Extensive bank protection is planned with the <br />development alternatives and is described in additional detail in <br />the EIS. Bank protection would continue to be added to the river <br />under the no-action alternative, but it would not be as exten- <br />sive. <br /> <br />The Sponsors consider the actual contract between the UVWUA and <br />Montrose Partners confidential. Reclamation has included <br />relevant information from the contract and proposal for <br />development services in the EIS. <br /> <br />The need for power section of the EIS has been expanded. <br />Additional information on this and the Colorado-Ute Electric <br />Association (Colorado-Ute) situation can be found in the <br />RESPONSli:S to COMMEN'l'S 1'-6 and OR-l. <br /> <br />Chapter 3 contains information on the economic effects of the <br />no-action and development alternatives on fishing and rafting. <br />These recreational uses are expected to increase in the future; <br />however, the increase will be limited by BLM and National Park <br />Service (NPS) land management plans designed to prevent overuse <br />and damage to resources. The management restrictions have been <br />considered in the analysis. <br /> <br />Efforts to develop an alternative acceptable to Western Colorado <br />Congress (WCC) are described earlier in Volume I of this FEIS. <br />However, proposals submitted by WCC have not been found to be <br />economically or financially feasible. <br /> <br />9. MR. BOB CORY: Concerning fisheries, with the Aspinall Dams <br />on the Gunnison River and the Dallas Reservoir and the <br />AB Lateral, there will be an improvement, especially in the <br />Uncompahgre River. The only bad thing I see is that there will <br />be less water for rafting. <br /> <br />RESPONSIi:: It is hoped that the fishery in the Uncompahgre River <br />will improve due to Ridgway Dam. The EIS recognizes a reduction <br />in rafting in the Gunnison River. <br /> <br />P-8 <br />
