Approximately 920 cfs will continue to be <br /> <br /> <br />div~ted through the Gunnison Tunnel to the South Canal, as <br /> <br /> <br />is now the case, ror combined irrigation-hydroelectric gene- <br /> <br /> <br />ration purposes. During the non-irrigation months, opera- <br /> <br /> <br />tion of the hydroelectric projects will change the flow in <br /> <br /> <br />the Gunnison River by extending the withdrawals to a year- <br /> <br /> <br />around basis. Agreements reached during the development of <br /> <br /> <br />the Curecanti Project established a protected flow of <br /> <br /> <br />200 cfs for the Gunnison River below the diversion tunnel. <br /> <br /> <br />Therefore, subject to water rights, operation or the pro- <br /> <br /> <br />posed hydroelectric projects would not divert flows rrom the <br /> <br /> <br />Gunnison River during the non-irrigation season until flows <br /> <br /> <br />in the river exceeded approximately 200 cfs. As described <br /> <br /> <br />in Exhibit A, historic flow data for the Gunnison River <br /> <br /> <br />indicates that adequate flows exist to allow diversion of <br /> <br /> <br />approximately 920 cfs on a year-around basis, while pro- <br /> <br /> <br />tecting the 200 cfs minimum flow downstream. <br /> <br />The hydroelectric projects propose to generate power and, <br /> <br /> <br />therefore, divert flow from the Gunnison River for 12 months <br /> <br /> <br />per year. However, as discussed later, it is anticipated <br /> <br /> <br />that occasional canal maintenance may require temporary <br /> <br /> <br />short-term shutdown of the facilities. <br /> <br />E-30 <br />
