<br />0377 <br /> <br />2.17 <br /> <br />would be considerably greater than for a base load facility (Sheaffer &'~land, <br /> <br /> <br />Inc., 1982); 3) the power produced could not be used entirely by a single con- <br /> <br />sumer and would therefore prdduce minimum direct benefits to several con- <br /> <br /> <br />sumers; and 4) the amount of power -produced is quite small in relation to its <br /> <br />time of availability and the additional cost of the facilities (Sheaffer & <br /> <br />Roland, Inc., 1982). <br /> <br />2.3 Mitigation Measures for Alternatives Considered in Detail <br /> <br /> <br />All water sales resulting from future contracts the Bureau may enter into <br /> <br />will be conducted and the water delivered, according to the Operating <br /> <br /> <br />Principles established for Ruedi Reservoir and adopted by the State of <br /> <br />Colorado, April 30, 1959 (as amended December ,30, 1959 and December 9, 1960). <br /> <br /> <br />The Operating Principles contain minimum streamflow requirements by season <br /> <br />and/or months, and these minima would continue to be enforced by the Bureau. <br /> <br />The minimum stream flows in the Fryingpan River below Rocky Fork shall not be <br /> <br /> <br />reduced below inflows to the reservoir or 39 cfs from November 1 to April 30, <br /> <br /> <br />and 110 cfs from May 1 to October 30, whichever is less. <br /> <br />A second mitigation measure was incorporated into the simulation of <br /> <br /> <br />operation of the reservoir for all alternatives. This mitigation measure <br /> <br /> <br />enhances winter streamflows in the Fryingpan River and provides for flood <br /> <br /> <br />regulation during the spring runoff. Target winter reservoir levels were set <br /> <br /> <br />based on historic operation of Rued! Reservoir. A maximum winter release was <br /> <br /> <br />then set for the months when target levels would be in effect. A rule was <br /> <br />added to the reservoir operation model as follows: <br /> <br />If the end of month content of the reservoir is above the target <br />level then increase the reservoir releases until the target level is <br />met. If releases exceed the maximum, then reduce releases to the <br />maximum winter release. <br /> <br />. <br /> <br />The maximum winter release was set at 120 cfs or sales level, whichever was <br /> <br /> <br />larger. Target levels were set as follows for the end of month content from <br /> <br /> <br />October to April. <br />
