<br /> <br />e <br /> <br />e <br /> <br /> <br />e <br /> <br />COLORADO WATER CONSERVATION BOARD <br /> <br />Alsbury Dam <br />West Divide Water Conservancy District <br />January. 1989 <br /> <br />Introduction <br /> <br />Alsbury Dam is owned by the West Divide Water Conservancy <br />District (District). It is located about 23 miles southeast <br />of Rifle. The dam is currently breached. The purpose of this <br />proposed project would be to restore the dam to a height of 25 <br />feet. which would create a capacity of 255 acre-feet in the <br />reservoir. <br /> <br />Problem <br /> <br />The water users below Alsbury Reservoir are in need of <br />supplemental water to increase hay production and to provide <br />an augmentation source for domestic wells in several rural <br />residences. This need is expected to increase in future years <br />so the rehabilitation of this reservoir is of vital importance <br />to the District. <br /> <br />Proposed Proiect <br /> <br />This project would consist of the reconstruction and <br />enlargement of the existing breached dam on the headwaters of <br />East Divide Creek in Mesa County. The proposed dam woUld be <br />25 feet high. which is 5 feet higher than the existing dam. <br />This increased height would allow the district to store the <br />maximum storm run-off capacity (for dam safety purposes). in <br />addition to their decreed storage capacity of 255 acre-feet. <br />The total estimated cost of this project is $70.000. <br /> <br />A technical issue associated with this project is that the <br />left abutment of the dam site is created by a huge. pre- <br />historic landslide mass about 1 mile wide and 2 1/2 miles <br />long. The Alsbury dam and reservoir are located at the <br />upstream. or south edge. of the landslide. Seven test pits <br />were sunk at the dam site and the reservoir during the <br />feasibility study to investigate the site and materials <br />available. This matter will be investigated further as final <br />designs for the project are prepared and a solution identified <br />before construction commences. <br /> <br />Proposed Financinq <br /> <br />District (capital reserve account) <br />CWCB loan (at 5 percent. 20 years <br /> <br />- $35.000 <br />35.000 <br />$70.000 <br /> <br />9052E <br /> <br /> <br />.... <br />
