<br />STATUS REPORT ON S.B. 439 <br />PROJECT STUDIES <br /> <br />Colorado Water Conservation Board <br />September 9, 1982 <br /> <br />Cache la poudre Project <br /> <br />S.B. 439 calls for the study of "an integrated project <br />upstream of the Town of Fort Collins on the Cache la poudre <br />River." Thus, only such storage facilities as would be located <br />on the mainstem of the Cache la poudre above Fort Collins and on <br />the South Fork and the North Fork of the Cache la poudre are <br />being considered. However, neither the existence of designated <br />wilderness areas nor the possible inclusion of the river in the <br />national wild and scenic rivers system has been taken as a <br />constraint on the siting of potential reservoirs. <br /> <br />The objective of the study is to analyze, at a reconnais- <br />sance level of detail, the engineering and economic feasibility <br />of alternative projects which could develop new water, improve <br />the management of already developed water supplies, and provide <br />hydroelectric power production. <br /> <br />The study is being conducted in two phases. During Phase I, <br />eight preliminary alternative pro;ects were identified and <br />evaluated. The preliminary alternatives included two single <br />reservoir projects and six multiple reservoir projects. The <br />results of the Phase I analyses were presented in an interim <br />report published in August and reviewed by the Colorado Water <br />Conservation Board (CWCB) at its August 16 meeting. <br /> <br />The Board selected three alternatives for further evaluation <br />in Phase II of the study. These are: <br /> <br />1. A pro;ect which would consist of terminal conservation <br />storage at Grey Mountain (200,000 acre-feet), with <br />upstream storage for hydropower production (1.18 MW) at <br />the Idylwilde site (200,000 acre-feet). This is <br />similar to the project studied by the U. S. Bureau of <br />Reclamation in the early 1960's. <br /> <br />2. A project which would consist of terminal conservation <br />storage at an expanded Seaman Reservoir (200,000 <br />acre-feet) on the North Fork, wi th upstream storage for <br />hydropower production (88 MW) at the Elkhorn Reservoir <br />site (196,000 acre-feet). <br /> <br />3. A single reservoir project, primarily for conservation <br />storage, at the Elkhorn site (196,000 acre-feet). <br /> <br />143 <br />fs/dft <br />
