The "best" condition <br /> <br /> <br />was assumed to be the highest level of discharge which could be sustained by <br /> <br /> <br />the reservoir over the entire year. The alternative was selected from pre- <br /> <br />vious operational studies for alternatives 6, 7 and 8, which minimize risk to <br /> <br /> <br />fish, wildlife and recreation. Alternative 6 was selected since it will pro- <br /> <br /> <br />vide an average year-round discharge of 70 cfs and at least a 50 cfs discharge <br /> <br />in the winter. <br /> <br />2.1.10 Alternative 10. Municipal/Industrial Sales Minimizing Risk to <br />Fish, Wildlife and Recreation Including Augmentation of <br />Hydropower <br /> <br />, <br /> <br />This alternative improves conditions for hydroelectric power generation <br /> <br />by augmenting winter releases. Increased winter releases also benefit the <br /> <br /> <br />fishing but may lead to decreased reservoir levels in summer months. Winter <br /> <br />flows (November through March) were augmented to the 90 cfs level. This pro- <br /> <br /> <br />vides a year-round minimum release from Ruedi Dam of 90 cfs. The maximum <br /> <br /> <br />augmentation required for hydropower in any year was 9,900 acre-feet with the <br /> <br /> <br />average annual augmentation being 8,500 acre-feet. Figure 2.9 shows typical <br /> <br /> <br />charts for reservoir level and instream flow in the Fryingpan River for <br /> <br /> <br />Alternative 10. <br />
