<br />OGu:~4 <br /> <br />II. Purpose of Studv <br /> <br />This study was conducted in order to analyze the feasibility of construct- <br /> <br />ing water development facilities to utilize the unused and unappropriated waters <br /> <br />of the Little Snake River in Wyoming for both in-basin and out-of-basin needs, <br /> <br />In-basin needs were identified by the staff of the Wyoming Water Development <br /> <br />Commission (WWDC). Possible in-basin uses could include: supplemental supply <br /> <br />for existin8 irrigation, full supply for new irrigation, domestic and municipal <br /> <br />use, and industrial use. Preliminary engineering plans were developed for al- <br /> <br />ternative reservoirs that could be constructed to meet the projected in-basin <br /> <br />needs for water. <br /> <br />This study also evaluates the feasibility of construction of diversion and <br /> <br />conveyance facilities to transport water from the Little Snake River basin to <br /> <br />the North Platte River basin for municipal use by communities along the North <br /> <br />Platte River in south central and southeast Wyoming. The transbasin diversion <br /> <br />plan would be similar in concept to the Stage III proposal of the City of <br /> <br />Cheyenne's water development project. Included in the study was the develo~- <br /> <br />ment Ot preliminary plans for diversion, conveyance, and storage facilities that <br /> <br />would be required to meet the potential out-of-basin needs as identified by the <br /> <br />staff of the ~,DC. <br />The following areas of interest were treated in this study: <br /> <br />Hydrology - A hydrologic analysis was conducted to determine water <br /> <br />resources which could be developed into viable water development proj- <br /> <br />ects. <br /> <br />Geotechnical - A geotechnical analysis was conducted to determine the <br /> <br />feasibility of alternative dam sites for development of storage fa- <br /> <br />cilities. <br /> <br />11-1 <br />
