The applicant proposes to create two ground water <br />ponds with a total surface area of 30.4 acres. The proposed reclaimed use of <br />these ponds is unclear but we believe they will be used for wildlife habitat. <br />Using an impoundment of water for recreational purposes, including fishery and <br />wildlife, has been defined in Section 37-92-103, CRS (1973), as putting the <br />water to beneficial use. Since the source of water for the ponds that will be <br />created by the gravel pit operation is ground water and the ground water will <br />be used beneficially, we require that a well permit be obtained from our <br />office. The well permit must be obtained prior to excavation of the gravel <br />pit. Otherwise, Coulson Excavating Co. will be in violation of Section <br />37-90-137, CRS (1973). Since the proposed gravel pit would be located in an <br />over-appropriated basin, the well permit could not be obtained until a court <br />approved plan for augmentation has been developed. <br />Coulson Excavating Co. has provided insufficient information concerning the <br />use of water in the mining operation. In order for us to comment, we would <br />need to know the quantities of water to be used for dust control, washing, and <br />other purposes. We would also need to know the sources of water for the <br />operation and the legal right to use these water sources. Coulson Excavating <br />Co. will not be able to use water from the pit for the mining operation unless <br />replacement water for the additional consumptive use is included in the plan <br />for augmentation. <br />The surface area of the pond that will be formed in the mining process is 31.4 <br />acres. The amount of water lost to the South Platte River basin due to evapo- <br />ration from this amount of water surface is approximately 80 acre-feet per <br />
