<br /> <br />, <br /> <br />/' <br /> <br />e <br /> <br />e <br /> <br />e <br /> <br />-2- <br /> <br />Gunnison Rivers, were reviewed. Diversion points downstream of the Gunnison River <br />confluence with the Colorado mainstem will only be considered. <br />b. Existing absolute and conditional water rights downstream of the Gunnison confluence will <br />be reviewed. <br />c. To avoid sensitive land uses such as wilderness and conservation areas, the feasibility of less <br />disruptive types of diversion facilities (e.g. infiltration basins and radial collectors) versus <br />diversion dams impounding flow will also be investigated. <br />d. The need for operational storage to enhance the reliability of the conveyance system will be <br />reviewed relative to the potential magnitude and location of facilities. <br />e. The intent of the Study is to size the project so that it is able to operate every year and <br />therefore, be economically sized for average annual diversion rates. The annual and seasonal <br />availability of flows and annual operation and maintenance (O&M) requirements for the <br />system will be analyzed. <br />f. In summary, potential diversion points upstream of the Gunnison confluence will only be <br />discussed qualitatively in relation to potential scenarios for developing the project in stages. <br /> <br />2. Water Treatment <br />a. The following treatment levels will be considered: <br />i. Match water treatment level to match the water quality of the receiving waterbody <br />ii. Enhance the pumped water quality to some level yet to be determined <br />b. Various possibilities for handling waste streams will be considered. <br /> <br />3. Pipeline Routes <br />a. The group concluded that 3 general corridors would be appropriate for this short duration <br />reconnaissance study and that an alternative in each corridor would be selected as being <br />"representative" of the potential alignments in each corridor. The three corridors will include <br />a northern corridor (north of the Flat Tops Wilderness area), a central corridor (along the 1-70 <br />corridor), and a southern corridor (extending up the Gunnison basin). The various routing <br />alternative alignments in each corridor will be discussed in the study narrative. <br />b. General alignment criteria will include: I) avoidance of National Parks, Monuments, and <br />Wilderness Areas; 2) only utilizing diversion points downstream of the Gunnison confluence; <br />and 3) encompassing a broad geographic range in the alignments. <br />c. Each alternative must be able to physically deliver water to the South Platte, Arkansas, and <br />Colorado river basins or there must be identified a potential for delivery via exchanges with <br />existing water users and their systems. Any potential exchanges will be approved by affected <br />parties and implemented in ways to avoid or offset potential impacts to other vested water <br />rights and/or uses. <br />d. It was recognized that southern Denver metro area and Douglas County have significant <br />long-term water supply issues and that this area may have the most significant need for long- <br />term reliable water supplies from the CRRP. <br />e. Exchanges could potentially involve Denver Water, the City of Colorado Springs, the City of <br />Pueblo, Southeastern Colorado Water Conservancy District and the Northern Colorado <br />Water Conservancy District systems if they are receptive to considering various options. <br />Each entity will be contacted before drawing any conclusions on the potential for <br />incorporating exchange possibilities in the Study. <br /> <br />Flood Protection.
