Please see the attached project <br />summary and map. <br /> <br />Backl!round <br />The DeWeese-Dye Ditch and Reservoir Company of Canon City owns and operates <br />DeWeese Dam which is located on Grape Creek about five miles north of Westcliffe in <br />Custer County. DeWeese Dam is a concrete masonry structure which consists of an <br />original structure built in about 1903 and two raises of the dam by four feet and eight feet <br />constructed separately in the years between 1903 and 1931. The present dam has a height <br />of 63 feet and impounds about 4,000 acre-feet of water which is used primarily for <br />agricultural and rural water supply. <br /> <br />The issue of concern is the condition of the top 12 feet of the dam which show <br />considerable spalling and cracking. Recent inspection reports by the State Engineer's <br />Office have indicated that storage restrictions will be imposed if the Company does not <br />take appropriate action to improve the condition of the two crest raise sections. <br /> <br />Feasibility Studies <br />The Company retained GEl Consultants of Englewood to conduct a feasibility study to <br />. include an assessment of the dam and an analysis of alternatives for any rehabilitation <br />
