<br />release for fishery purposes in August and September would be 700 cfs <200 <br /> <br />cfs - historic; 100 cfs - cold and warm fishes; 400 cfs - warm fish). <br /> <br />The preliminary data on the release requirement for endangered fish <br /> <br />does not display the years during the study period in which a 500 cfs <br /> <br />release in August and September must be made. Because the disaggregated <br /> <br />data were not available arid because of the preliminary nature of these <br /> <br />data, it was assumed for the purposes of this study that the 500 cfs <br /> <br />release in August and September for endangered fishes would be made in <br /> <br />those dry years of the study period with flow exceedance probabilities <br /> <br />between 80~ and 90%. The assumption is that Blue Mesa storage releases <br /> <br />would not be made for endangered fish purposes in the 90~ or greater <br /> <br />exceedance years or drier years. It is not clear, however, whether the <br /> <br /> <br />proposal to maintain the 2000 cfs at Westwater in 9 years out of 10 <br /> <br /> <br />assumes that nQ storage releases would be made in 90% exceedance years, or <br /> <br />that releases would still be made in such years, but would not be <br /> <br />increased over historic levels by more than 500 cfs during August and <br /> <br />September even though the flow at Westwater with the release fell below <br />2000 cfs. <br /> <br />J. Boating Flows <br /> <br />A minimum stream flow of 600 cfs from June to September for boating <br /> <br />purposes in the 29-mile reach has been proposed. The protection of such a <br /> <br />minimum stream flow with Blue Mesa storage releases would increase the <br /> <br />WBLA, Inc. 1909 Broadway, #3, Boulder, Colorado 80302 <br /> <br /> <br />23 <br />
