You requested we review portions of <br />their application for permit to the Colorado Division of Minerals and Geology, CMLRB, <br />and Montrose County. You directed us to conduct field inspections, water tight and <br />registered well location and adjudication, review and inspect the property to determine if <br />the proposed excavation would impact exis[ing water resources on the Mesa. <br />We have resided on Sprim~ Creek Mesa for 25 years and have investigated groundwater <br />conditions 'in numerous areas for subdivision applications, gravel pits, septic <br />contami+7ation and ditch artd canal losses. We have been, and are currently, retained by <br />gravel operators to advise them ss to.groundwater impacts and litigation, reclamation and <br />pit s[ability. In addition, we have assisted in water rights and evaluation of additional <br />water for Silver Springs Trout Farnt (located 1/3 mile east of the proposed pit), <br />supervised construction of alluvial wells along LaSalle Road, which supply a large <br />mobile home park, and observed tl,e irrigation dio•ersion and application of irrigation <br />water practices o7t the Mesa for many years. <br />The pit is proposed for location on the east half, east half, Section 24, T49N, R10W, <br />NMPM. 'it is bounded on the north by LaSalle Road, west by 6175 Road and south by <br />relatively new subdivision of larger than average homes. The pit would be bounded on <br />the east by the Bean Ranch on. the southern '/. of the pit, and the Nation's "Hillside <br />Horttes[ead", along the northern %. mile. The propert}• currently is imgated farm ground, <br />attd one of the {arger contiguous operational fauns left oa the mesa. The current owner is <br />the Gearge family. The grourtd surface slopes gently from southwest to north and <br />northeast, with irrigation warer being derived from the CI and C]N Laterals. Irrigation <br />water is spread via row crops and/or t7ood irrigation in a northerly and northeasterly <br />direction. The Bean Ranch to the east contains approximately 100 acres of irrigated farm <br />ground. The entire land parcel west of 6 f 75 Road is similaz in nature in that it is all <br />irrigated pasture and craplar7d. Again, the ground slopes gently from southwest to <br />northeast toward t17e pit. <br />
