<br />. <br /> <br />. <br /> <br />. <br /> <br />COLORADO WATER CONSERVATION BOARD <br />721 State Centennial Building <br />1313 Sherman Street <br />Denver, Colorado <br />January, 1986 <br /> <br />Great Western Dam Project <br />(City of Broomfield) <br /> <br />Introduction <br /> <br />A loan in the amount of $2,156,000 was authorized for this <br />project under HB 1102 in the 1983 legislative session. Since <br />that time the city. has re-evaluated the project and concluded <br />that it should be expanded from the 9,100 acre-foot capacity <br />recommended in 1983 to a 12,000 acre-foot capacity. <br /> <br />Problem <br /> <br />The City of Broomfield must enlarge the spillway of the <br />Great Western Dam to meet dam safety requirements. In addition, <br />the reservoir's storage capacity needs to be increased so that <br />the city's current water rights can be developed to meet the <br />increasing demands of its water users. The increased water <br />demands are due to the 3 percent growth per year that the city is <br />currently experiencing. <br /> <br />Project Study <br /> <br />Subsequent to the Board action taken on this proposed <br />project in 1983, the City of Broomfield fully funded an amended <br />feasibility study which was prepared by Rocky Mountain <br />Consultants, Inc. That amended study is the basis for the <br />recommendation on this project. <br /> <br />Proposed project <br /> <br />The amended study determined that the City of Broomfield <br />should construct a new spillway at the Great Western Dam which <br />would pass the probable maximum flood and enlarge the reservoir <br />to a capacity of 12,000 acre-feet. Such an enlargement would <br />require raising the existing dam embankment by 34 feet. It is <br />anticipated that these improvements will satisfy Broomfield's raw <br />water storage requirements until about the year 2015. <br /> <br />501 <br />gwd/fa <br />
