<br />OWENS CREEK RESERVOIR ON BUZZARD CREEK <br /> <br />PROJECT RE-EVALUATION <br /> <br />e <br /> <br />In the interest of water project development and resource management <br />reflecting present standards and changing demands, this request is <br />made by Battlement Mesa Water Conservancy District, West Divide Water <br />Conservancy District and Ute Water Conservancy District. <br /> <br />PURPOSE: To . determine the quanti ty, reI iabili ty and cost of water <br />storage for the following multiple beneficial applications. <br /> <br />I) Domestic water supplies in the Ute Water and West Divide <br />Water Conservancy Districts. <br /> <br />2) Supplemental irrigation supplies in the Battlement Mesa and <br />West Divide Water Conservancy Districts. <br /> <br />, <br />3) New recreational opportunities and possible fish and wildlife <br />benefi ts including habitat enhancement for the recovery of the <br />endangered Colorado River fish species. <br /> <br />SCOPE OF WORK - PHASE I <br /> <br />I) Prepare reconnaissance cost estimate for Owens Creek Dam <br />(earth fill structure 25,000 acre-foot reservoir configuration). <br />as presented in Feasibility Report dated June, 1967. ~ <br /> <br />2) Compile all previous stream flow records from 1929 to date, <br />correlating the periods for which no historical records exist. <br /> <br />3) Determine design flood in accordance with criteria <br />established by the Office of the State Engineer. <br /> <br />4) Determine the "hazard" or dam classification for the site. <br /> <br />5) Quantify project demands to be included in operation studies. <br /> <br />6) Conduct an appraisal-level hydrologic operation study to <br />determine required reservoir size and yield. <br /> <br />7) Prepare appraisal-level design and cost estimate for earth <br />fill and roller compacted concrete dams to accommodate reservoir <br />sizing determined in Task 6. <br /> <br />8) Prepare appraisal-level design and cost estimate for Divide <br />Creek aqueduct. <br /> <br />9) Repeat Tasks <br />aqueduct sizing <br />anticipated. ) <br /> <br />5, 6, <br />and <br /> <br />7 and 8 to optimize <br />water allocation. <br /> <br />reservoir sizing, <br />(One iteration <br /> <br />e <br />
