<br />: <br /> <br />e <br /> <br />. <br /> <br />ATTACHMENT I <br /> <br />GROUND WATER RECHARGE AND MANAGEMENT PROJECT <br /> <br />FOR <br /> <br />SAN LUIS VALLEY WATER CONSERVANCY DISTRICT <br />835 1st Avenue, P.O. Box 43 <br />Monte Vista, Colorado 81144 <br />Phone (719) 852-2315 <br /> <br />January 7, 1991 <br /> <br />PURPOSE: <br /> <br />Collect data concerning performance of artificial ground water <br />recharge and resulting under ground storage and use it to help <br />educate water users concerning the benefits of recharge and provide <br />some basic data necessary to determine the need for an integrated <br />water management plan for the San Luis Valley. Also construct a <br />major recharge structure to facilitate ground water storage with <br />winter surface water diversions. <br /> <br />LOCATION: <br /> <br />The location of the project is within the boundaries of the <br />San Luis Valley Water Conservancy District and generally encompass- <br />ing the areas in the San Luis Valley traversed and irrigated by <br />waters of the Rio Grande. <br /> <br />HISTORY AND NEED: <br /> <br />During recent years the ground water levels and pressures in <br />the artesian aquifer of the San Luis Valley have varied widely. <br />Also during this period the Rio Grande Basin has, through the <br />spilling of Elephant Butte Reservoir, eliminated a major Rio. Grande <br />Compact debt and seen the Closed Basin salvage project begin to <br />deliver significant amounts of water to the river. These events <br />have resulted in many people recognizing that through better water <br />management in the San Luis Valley, more water can be made available <br />to senior and junior water rights in Colorado that have been <br />previously curtailed to meet Rio Grande Compact obligations to <br />downstream States. <br /> <br />One of the primary resources that can be managed to allow more <br />full utilization of water rights is the underground aquifers in the <br />San Luis Valley. By storage of surface water rights in the <br />aquifers, the aquifers can function as under ground water storage <br />reservoirs. The filling of the aquifers has historically occurred, <br />but in an unplanned manner that has resulted in overfilling in some <br />areas and under filling in other areas. One of the objectives of <br />this project is to assist in developing a better understanding of <br /> <br />1 <br /> <br />EXHIBIT A <br />
