<br />. <br /> <br />COLORADO WATER CONSERVATION BOARD <br />823 State Ce~tennial Building <br />1313 Sherman Street <br />Denver, Colorado 80203 <br /> <br />January 6-7, 1983 <br /> <br />Hyannis ~eak Reservoir <br />(Meyering Livestock Co.l <br /> <br />Introduction <br /> <br />The proposed Hyannis Peak ~eservoir would be located near the <br />headwaters of the Middle Fork of Arapahoe Creek, approximately 25 <br />miles south of Walden. The dam would be about 80 feet high with <br />a crest length of about 350 fe~t. The storage capacity of the <br />reservoir would be just over 2,000 acre-feet. The reservoir <br />would lie entirely within the ~outt National Forest. <br /> <br />Problem <br /> <br />The Meyering Livestock Company suffers late season water <br />shortages for hay production. This problem can be alleviated by <br />the construction of the subject reservoir. The reservoir would <br />provide supplemental irrigatio~ water to 5,300 acres of land <br />owned or leased by the company. <br /> <br />Project Study <br /> <br />The Meyering Livestock Company submitted an application in <br />March, 1980. The ewCB staff subsequently met with the owner and <br />his conSUlting engineer on several occasions to discuss the pro- <br />ject. One such meeting was at the proposed project site, At the <br />December, 1981, meeting the CWeB authorized matching funds for a <br />feasibility study on the project. That study has been completed <br />by Rocky Mountain Consultants, Inc., and is the basis for recom- <br />mendations on this project. <br /> <br />proposed Project <br /> <br />The Hyannis Peak Reservoir would be created by the construc- <br />tion of a rock fill dam with a maximum height of 80 feet above <br />streambed, a crest length of 340 feet, and a crest width of 10 <br />feet. The outlet works would be a gated, 30-inch reinforced <br />concrete pipe. The emergency spillway would be through an <br />adjacent saddle. The total estimated cost of the project is <br />$850,000. <br /> <br />The sponsor has a conditional storage decree in the amount <br />of 2,122.7 acre-feet which was adjudicated in February, 1972, <br />with a priority date of September 16, 1963. The Division <br />Engineer advises that storage in the reservoir would occur under <br />the terms of the U. S. Supreme Court decree in all but the very <br />driest years. <br /> <br />600 <br />Hyannis/Res <br />
