<br />00871.5 <br /> <br />Fish and Wildlife Comments <br /> <br />peak flows, the Service, in cooperation with the Recovery Program, will determine if the <br />proposal satisfies the requirements ofthe PBOo Although the Service can provide technical <br />assistance to the Executive Committee, it would be inappropriate for the Service to specify <br />which alternative(s) should be selected for detailed analysiso . <br /> <br />Absent specific guidance from the study, I offer some suggestions for completing the CFOPS <br />study process and developing an adaptive-management process to implement the best features of <br />selected alternatives. The following suggestions should be considered only as the beginning of a <br />negotiation process. <br /> <br />EO'" <br /> <br />II <br /> <br />1) The Phase 2 Report should be finalized by the consultant, incorporating appropriate <br />comments from the Executive Committee and the Recovery Program Water Acquisition <br />Committee. <br /> <br />2) <br /> <br />The Executive Committee is the appropriate forum for an interdisciplinary review of the <br />study's results and subsequent identification and formulation of an augmentation <br />proposal. The Committee should follow an adaptive-management process similar to the <br />current coordinated reservoir operations (CROS) process to monitor river flows and <br />coordinate reservoir releases to augment flows. Using this model, some combination of <br />the "Share the Pain"/Modified "Share the Pain" and "Insurance Pool" alternatives appear <br />to provide the best solutions to meet short-term objectives. However, no reasonable <br />alternative should be eliminated before the Committee has adequately assessed its <br />individual merits and evaluated it against other options. For example, the proposal set <br />forth by the Ray Tenney on behalf of the west slope water users appears to have merit <br />and should be considered by the Executive Committee. <br /> <br />3) The Executive Committee should begin discussions and hold several work sessions to <br />identify the most feasible alternatives or portions ofthese alternatives and use them as <br />sideboards for an adaptive-management process. Once identified, an agreement should <br />be negotiated among affected parties to implement the alternative(s) identified. <br /> <br />4) Any new projects (including all feasibility studies, engineering design and construction) <br />would be funded outside the Recovery Program, similar to that which East Slope water <br />users are carrying out on Sulfur Gulch Reservoir. <br /> <br />5) <br /> <br />The Service recognizes that providing 20,000 acre-feet of water for peak augmentation <br />will be difficult and will take a great deal of cooperation and trust, which has been <br />demonstrated so far in the existing CROS and late summer flow augmentation efforts <br />undertaken by the Recovery Program. We have all learned hard lessons during the <br />current drought, which were expressed at the last Executive Committee meeting. A <br />major concern that was not addressed in the Phase 2 Report is a situation where an above <br />-average water year occurs after a period of drought. A situation could occur where un- <br />augmented flows in the target range of 12,900 to 26,000 cfs would trigger peak-flow <br />augmentation. However, reservoir operators would be reluctant to bypass inflow because <br />reservoir levels are low due to the preceding drought. I believe that the Service would <br /> <br />P:\Data\GEN\CWCB\19665\Repon Phase 2\Technical Memorandum No. 12\Appendix B.doc <br /> <br />23 <br />
