storage are available between the crest of the inlet at elevation 5520.0 feet and the top of the fabridam;at elevation 5531.0 feet. Leyden Lake is an irrigation water~~torage reservoir on Leyden Creek northwest of Denver. There are' approximately 550 acre-feet of uncontrolled storage between the spillway crest at 5,612 feet and the crest of the dam at elevation 5,620 feet (References 22 and 23). Bear Creek The completion of the Bear Creek Dam j4st downstream of the Town of Morrison has greatly affected the peak discharges of Bear Creek. Designed by the COE, the dam provide~ a flood control reservoir that intercepts flows from areas in the upper and middle parts of the basin. At the Bear Creek Reservoir, peak flows from the 100- year event have been reduced from 30,000 cfs to approximately 1,000 cfs through storage in the reservoir. There has been some straightening and enlargement of the channel downstream of the dam to reduce flooding in the lower, more developed areas of Bear Creek (References 9 and 24). Cherry Creek Cherry Creek Dam and Cherry Creek Reservoir were constructed by the COE, Omaha District, in 1953. The project, located immediately upstream of Denver, was constructed at a Federal cost of approximately $14.7 million and provides protection for Denver from flash floods on Cherry Creek. The reservoir has a flood-storage capacity of 79,960 acre-feet. During tije June 1965 flood of record, the project prevented an estimated $1~0 million in flood damages. During the 1973 flood season, it prevented an additional $27 million in damages (Reference 4). Retaining walls have been constructed along the Cherry Creek channel downstream of First Avenue to the confluence with the South Platte River. Portions of Cherry Creek, between First Avenue and the South Platte River, and in the vicinity of South Monaco Street Parkway, have been improved and rec~ntly rehabilitated to carry much of the 100-year floodflow within: the channel banks. Earthen berms have been constructed south along Cherry Creek between South Holly Street and upstream of South Monaco Street Parkway, which have minimal effect on the 100- and 50~-year flood. Westerly Creek . The Kelly Road Dam on Westerly Creek was constructed by the COE in 1954 (Reference 4) to control storm! runoff; however, the urban development upstream has lowered the jprotection level. A recent rehabilitation project has restored somewhat the structure's ability to attenuate flood peaks. Chan~el improvements are underway downstream .of Kelly Road Dam. When completed, they will further reduce the flood hazard between 11th Avenue and Stapleton International Airport. 12
