• 17 • EXHIBIT G WATER INFORMATION WEST END GRAVEL PIT No. 1 WEST END GRAVEL COMPANY SEu SEC 11, T66N, R15W, NL~M The primary water resource is the San ?viiguel River which flows from northeast to southwest within 100 feet of the south permit azea boundary. The "Doing "irrigation ditch's right-bank diversion is upstream about 1,800 feet to the northeast from the perntit area's southeast comer, and its flow parallels the permit azea south boundary, crossing it at four locations. Just within the permit azea south boundary a '/,-acre triangular stockwater pond receives the Doing Ditch and in tom dispenses it westwazd at its northwest corner. The stockwater pond is the source of dust abatement and wash plant water operations at the site. Consumption averages 384 IVUGallons per day doting full scale operation of the wash plans which is about 66 , 560 M/Gallons per year. Doing Ditch then diverts azound the north end of an oval "operations" settling pond located in the north-to-south flowing natural drainage that bisects the permit area, intercepting the flow of that drainage, and continues westerly to the host owner's irrigated fields west of the permit area. There is no natural outfall from either the settling pond nor the N--S central drainage ditch since both aze diverted to the Doing Ditch for agricultural consumption. The "CC" irrigation ditch diverts from the San Ivliguel River several miles upstream from the site and passes 600 to 800 feet north of and 200 feet in elevation above the permit aeea's north boundary. Seepage from the CC Ditch and, in the wet season, from the mesa above the north canyon rim, percolates into the N--S drainage across the permit area keeping it wet throughout the dry season. The sub-strata beneath the gravel terrace deposits and above the unweathered silty claystone of the Morrison formation is also kept moist from that ditch seepage. No other normal ground water horizon is known to exist at the site, other than the described irrigation-induced wet zone between the alluvial gravels and the practically = _ impervious claystone bedrock. Doing Ditch, being just south of and below the floor of the site's alluvial bench gavel deposits, tends to intert;ept the majority of this subsurface seep and any surface runoff from the operations site and conducts it westerly to the imgated 5elds. Doing Ditch is owned and operated in its entirety by the host landowner, George Gloster. Proposed operations shall have no effect upon either the irrigation ditches nor the natural flow of underground "seep" water, nor upon the natural flow of San Miguel River. Post-mining topsoiling and re-vegetation of the operation site shall put the ground surface in closer proximity to the described sub-surface seep-zone, where conceivably the vegetation root zone shall extend into and benefit from the moist substrata.
