0040 2. I:! downstream. This would helve a severe impact on the Frylngpan River be-low "the.. , dam, eliminate most of the spawning areas for brook dnd brown trout and inun~ date a portion of the highest quality fishing segment of the river. This alternative would also require nn operating agreement with the Bureau for modifying the daily release pattern from the dam. This would result in a higher operation cost incurred by the Bureau for the dam's opera- tion of the afterbay to control the daily variations in release patterns. This alternative would produce a peak power production of approximately 35 megawatts for a period of about 1-1/2 hours per day. The total annual power production would be approximately 20 million kilowatt hours (Sheaffer & Roland, Inc., 1982). A peaking hydropower facility was rejected for-several reasons: 1) Construction of an afterbay would cause significant adverse impacts on the Fryingpan River below the dam; 2) the operation and maintenance requirements would be considerably greater than for a base load facility (Sheaffer & Roland, Inc., 1982), 3) the power produced could not be used entirely by a single con- surner and would therefore produce minimum direct _benefits to several con- sumers; and 4) the amount of power produced is quite small in relation to its time of availability and the additional cost of the facilities (Sheaffer & Roland, Inc., 1982). 2.2.2 Sales of Water to Exclusive Categories Four alternative kinds of water sales were considered in addition to . municipal/industrial sales, i.e. (1) sales for agricultural purposes only, (2) sales for municipalities only, (3) sales for industrial use only, and (4) sales only for fish, wildlife and recreation purposes. It was reasoned that since agriculture currently comprises approximately 70 percent of Colorado water diversions, agricultural demand should be satisfied with additional Ruedl water, thus allowing other existing water supplies to meet the municipal, industrial, fish and wildlife, and recreation demands. However, the agricultural community has developed its water supplies to the point where additional supplies from Ruedi are not needed, or more importantly, are not cas't competitive. In the absence of any agricultural demand for water, this alternative was eliminated. .
