Two Forks dam, as proposed by Denver Water and the Metropolitan Water Providers, was <br />to be located in Waterton Canyon on the South Platte River about one mile downstream from <br />its confluence with the North Fork of the South Platte. The multicurvature thin arch concrete- <br />dam would have been 615 feet high with a crest length of about 1,700 feet. The reservoir cre- <br />ated by Two Forks dam would have had an active storage capacity of 1.1 million acre feet, <br />with a surface area of 7,300 acres and a perimeter shoreline of about 100 miles. The reservoir <br />would have inundated about 21 miles of the South Platte River and about 9 miles of the North e.- <br />Fork. Two Forks reservoir would have provided a firm water supply yield of 98,000 acre-feet— _ - Pei-year , with 42 percent of the yield derived from the Blue River, 33 percent derived from the= _" 7 <br />South Platte, and about 25 percent from the Fraser and Williams Fork rivers. <br />U CAT[ ON A .. � _ <br />Y 7 A <br />�_.�.. <br />
