In this study several feasible alternatives are developed for repair of the dam embankment and <br />inlet ditch. The preferred alternative is Alternative 2, the reconstruction of the upstream slope <br />and dam crest and installation of a toe drain. The preferred alternative for the ditch repair will <br />install a flow restrictor in the ditch to direct surplus flood flow into a pre-existing ditch spillway <br />section, and also reconstruct the ditch to improve ditch bank freeboard and safety by <br />removing trees growing in the ditch and ditch banks. <br />STUDY AREA DESCRIPTION <br />The Bowles No. 1 Dam and Reservoir is located in the southwest metropolitan area of <br />Denver, Colorado, east of the intersection of West Belleview Avenue and South Wadsworth <br />Blvd. (South Carr Street). The reservoir is situated within the jurisdictions of the City of <br />Lakewood and the City and County of Denver. The Company owns the dam and reservoir, <br />and has easements for its inlet ditch and several outlet ditches used for delivery of water to its <br />shareholders. The Company's facilities are shown on Figure 1. <br />The reservoir is off-channel, and derives its water supply from Bear Creek near the Town of <br />Morrison. Watec is conveyed first through the Harriman Ditch to the vicinity of Harriman <br />Reservoir by Denver Water, and then through the inlet ditch to the Bowles No. 1 Reservoir. <br />Additional water supplies are conveyed from Bear Creek through the Bowles No. 1 Reservoir to <br />three other reservoirs on the Bowles system, which are operated by the Patrick/Bennett <br />Reservoir Company. The inlet ditch to Bowles No. 1 Reservoir is also used to convey direct flow <br />and storage water to other entities under an operations and maintenance agreement. <br />Historically, the Bowles No. 1 Reservoir water was used for irrigation of row crops, hay fields <br />and pastures on and in the vicinity of the Bowles No. 1 Reservoir and the Grant Farm, <br />portions of which are located in what are now the Grant Ranch Development, Southwest <br />Plaza and Clement Park. The current primary uses for the reservoir include irrigation of the <br />Grant Ranch Development parks and streetscape areas, irrigation supply for two golf <br />courses (public and private), irrigation of pasture grass for a number of private residences <br />and ranchettes, replacement of evaporation and seepage losses from other reservoirs on the <br />Bowles system but not a part of the Company, and for recreational uses. The water users and <br />service area are generally located south of the Bowles No. 1 Reservoir toward Coon Creek and <br />east toward the South Platte River. The general service area is also shown in Figure 1. The <br />2 <br />
