SUNDAY MINE COMPLEX-HYDROGEOLOGIC REPORT <br /> Colorado Division of Water Resources (DWR) data do not indicate the presence of springs, <br /> reservoirs, or other surface water features mapped within two miles of the SMC. The Sunday <br /> Mines Complex is mapped to be within a state wetlands boundary as defined by the Division of <br /> Wildlife National Wetlands Inventory Mapper (see Figure 5-2). The state wetlands boundary is <br /> an area that is defined as having riparian vegetation. The intermittent and ephemeral streams <br /> supplying Big Gypsum Creek and Disappointment Creek are mapped as riverine habitats. There <br /> are a few wetland ponds mapped as freshwater ponds and freshwater emergent wetlands within <br /> a one-mile radius of the SMC permit area on the north ridge towards Gypsum Valley and the <br /> south ridge towards Disappointment Valley, the largest being two ponds 0.35 miles to the north <br /> of the West Sunday Mine Portal in Gypsum Valley. The pond area is mapped at 1.38 acres of <br /> freshwater ponds and 1.91 acres of freshwater emergent wetlands according to the National <br /> Wetlands Inventory Mapper. These features have not been field inspected. <br /> Precipitation that falls onto the property will run off, be consumed as evapotranspiration, or <br /> infiltrate into the shallow soils. A portion of precipitation may percolate into the soils beyond the <br /> root zone, likely becoming subflow and recharging the shallow groundwater system. <br /> PRM maintains a stormwater discharge permit (no. COR-040223) with the state of Colorado. <br /> Site stormwater control structures are maintained; these best management practices are <br /> described in the site stormwater management plan. <br /> 6.0 WATER USE <br /> Water usage in the region is primarily from surface water sources, but locally, groundwater <br /> supplies are used for domestic purposes where shallow alluvial or bedrock aquifers are present. <br /> For example, in Monticello, Utah, the bulk of the town's water supply is from surface stream <br /> runoff from the Abajo Mountains. Groundwater wells completed in the alluvial and D aquifers <br /> provide water to outlying residents and ranches. In La Sal, Utah, to the north, most residents are <br /> supplied by private wells completed in the D aquifer; irrigation water is mostly seasonal runoff <br /> from the La Sal Mountains. In Naturita and Nucla, Colorado, source waters are primarily surface <br /> waters from the San Miguel River and tributaries. <br /> Within two miles of affected lands associated with the SMC there is very little water usage. Most <br /> of this area is public land administered by the BLM. The area is not occupied by humans on a <br /> day to day basis; no residents or ranches exist in this area.
