<br />GEER CANYON (Con"n~d) <br /> <br />municipal water service, industrial water needs. stream <br />fishing, electrical power requirements and other such <br />general needs as flood control, improving water Quality <br />and recreation. <br /> <br />With the formation of the Districl. the Board of Directors <br />adopted the following goals and Objectives: 1) Protection <br />of existing decrees in the Basins: 2) Provide additional <br />water storage; 3) Modification of irrigation systems to <br />prO\lide better management and higher efficiency; 4) Meel <br />water quality standards without negatively affecting water <br />users. <br /> <br />After working nine years to develop the overall water <br />management plan, it was determined that the needs of all <br />basin water users as outlined above can be mel by the <br />construction 01 Coftintop Reservoir and Geer Canyon <br />Reservoir. <br /> <br />Physical Facts and FIgures: <br />Height. length and type of dam: Height- 260 It. length <br />- 2250 fl.; Type - earth-rock fill <br />Storage capacity (A.

This involve- <br />ment and commitment to develop additional firm yield 01 <br />these water rights led to the initiation of a reconnaissance <br />level Investigation of a reservoir site in South Park early in <br />1978. In August 1979. an agreement was entered Into with <br />the City of Aurora to Cooperate on construction of water <br />storage facUities In Park County. :To this end. Aurora has <br />commenced construction of Spinney Mountain Reservoir <br />on the Middle Fork 01 the South Platle River and Thornton <br />Is completing the site selection process of an additional <br />reservoir most likely to be located on Tarryall Creek. To <br />date, Thornton has Informed Park County Planning <br />Officials and met With the Colorado Department of Natural <br />Resources to describe the progress on th is project. <br /> <br />The Thornton reservOir is preliminarily sized for ap- <br />proximately 20,000 acre-feet capacity and will be used <br />primarily for municipal waterstorage. Secondary benelits <br />will include recreation and possible hydro-electric power <br />generation. There is some possibility that other enllties <br />could also participate In this project as the final design and <br />sizing has not as yet been completed. To this end, interest <br />by other parties lor Joint participation will be solicited. <br /> <br /> <br />Physical Facts and Figures: <br />Not Available. <br /> <br />Proposed Sources of Funding: <br />City 01 Thornton. <br /> <br />For Further Information Contact <br /> <br />Lloyd J.
