<br />. <br /> <br />I <br /> <br />..1 f .. f <br />'!~f;t'i!ate an increase in natural reproduction in the l4-mile <br />reach of the Fryingpan River below the dam, such that it <br />should be managed as a wild trout fishery. <br /> <br />(14) The Rocky Fork Campground immediately below Ruedi <br />Dam was destroyed by construction of Ruedi Dam and Reservoir. <br />The campground consisted of four family units, a water system, <br />and sanitary facilities. <br /> <br />(l5) An archeological survey was conducted at Ruedi Reservoir <br />by the University of Denver's Department of Anthropology in <br />June 1963. Six sites produced identifiable artifacts, but <br />these archeological materials were very limited, and it was <br />recommended that no further work be performed. Four of these <br />sites were inundated by the reservoir. <br /> <br />. <br /> <br />(16) The construction of Ruedi Dam required the acquisition <br />of the Ruedi-Smith Creek range allotment in the White River <br />National Forest. This allotment totaled 7,062 acres and <br />produced 133 animal use months (ADM's) of forage annually. <br />The 798 acres of private land used in connection with this <br />land was acquired as recreational lands. A total of 900 <br />acres of private rangelands were taken out of forage produc- <br />tion for livestock. In addition, 370 acres of private irri- <br />gated land in production of alfalfa and other tame hay were <br />removed from cultivation. <br /> <br />(17) Ruedi Reservoir, and its associated recreation facili- <br />ties, accommodated between 60 and 70 percent of the visitor- <br />day recreation use in the Fryingpan River drainage between <br />1970 and 1972. Ruedi Reservoir generated 49l,347 visitor <br />days between the years of 1970 through 1974. <br /> <br />b. Unique Impacts <br /> <br />(1) Initial studies conducted on the l4-mile section of the <br />Fryingpan River below Ruedi Dam indicated that this section <br />is still one of the most productive in the State (Colorado <br />Division of Wildlife, 1972). Ruedi Dam allows control of the <br />Fryingpan River below the damsite. Controlled flows have <br />(1) increased success of spawning, (2) caused plant cover <br />to become more permanently established, and (3) stabilized <br />water quality and temperatures except for normal seasonal <br />changes. Stream temperatures for approximately 2 miles <br />below the dam have been stabilized as a result of dam <br />operations. Summer temperatures are an average 120 F cooler <br />and winter temperatures are warmer than before construction. <br /> <br />. <br /> <br />IV-54 <br />
