<br />Mr. Hal Simpson <br />State Engineer's Office <br />October 14, 1993 <br />Page 6 <br />The well map does indicate there is potentially one well, Permit No. 14172R, <br />within 600 feet of the perimeter of the proposed gravel mining. The location <br />of Well No. 14172R will be verified in the field to determined if it is <br />within 600 feet of the mining operation. A waiver agreement will be obtained <br />from the well owner if it is within 600 feet of the proposed gravel pit <br />perimeter. <br />F. CONCLUSIONS AND RECOl~NDATIONS <br />1. Excavation of the gravel at the site will be done with a floating <br />dredge. A total of eight acres of lake surface will result from the <br />first year of operation. Additional exposed water surface, 1.4 acres, <br />will result from the wash plant settling ponds and the generator cooling <br />water return ditch. A total 90.7 acre-feet of evaporation is expected <br />for the first year. <br />2. Other water uses will include water diverted for dust control, 12.5 <br />acre-feet; water retention in the excavated material, 23.6 acre-feet; <br />and water used for concrete production, 7.7 acre-feet. <br />3. The source of replacement water is water associated with the Buffalo <br />Creek Ditch (aka: Buffalo Canal). Approximately 31 acres of alfalfa <br />will be dried up which are irrigated by the Buffalo Canal. The dry up <br />will provide 84.7 acre-feet of water back to the stream system which <br />will offset the projected maximum annual consumptive use of the mining <br />operation of 84.4 acre-feet. <br />4. The site sits back from the river approximately 4000 feet and, <br />therefore, there is a delay in the timing of the depletions as they <br />reach the river. However, it is proposed in this plan that replacements <br />will be done during the irrigation season. <br />5. There appears to be one well which is within 600 feet of the proposed <br />gravel pit. A wavier agreement will be obtained from each well owner <br />having a well within 600 feet. <br />6. The applicant will use the attached accounting form to keep record of <br />monthly water use. These forms will be made available to the Water <br />Commissioner or the Division Engineer upon request. <br />7.. This plan is requested for one year with the option for renewal. <br />8. An annual report will be supplied to the State Engineer. <br />
