G -2. GROUND AND SURFACE WATER INFORMATION: <br />1. Sources of Ground Water on site or potentially affected by operations on site: None. There are no <br />wells on the site. Table G -1 lists recorded wells located within % mile of this site.4 Mining at this site <br />will be limited to depths of approximately 60 feet below existing ground level. This places mining well <br />above the known water table,5 including any alluvial aquifer of the San Juan River. Construction of <br />bridge and access road in valley bottom will not impact sources of ground water, based on standard <br />engineering design and activities. <br />2. Sources of Surface Water on site or potentially affected by operations on site: <br />• Sources within %2 mile of the site are shown on Table G -1. <br />• The only source of surface water on the site are the Rio Blanco and San Juan River. The small ravine entering <br />the property from the east permit boundary carries water only immediately after storm events. No springs or <br />potential for springs have been identified. <br />• The San Juan River is a major tributary of the Colorado River; the Rio Blanco is a minor tributary of the San <br />Juan. From this point the San Juan flows into Navajo Lake in New Mexico. <br />• A single irrigation ditch diverts water from the San Juan River during irrigation season, and has a small amount <br />of water for year -round domestic and animal watering use; the semi - improved headgate for the ditch is located <br />immediately north of the bridge abutment for the access road. The access road is designed, including an open - <br />floor (no- bottom) box culvert, to allow the ditch owner to have access to operate and maintain the ditch and the <br />intake from the river, in accordance with a court - ordered, recorded agreement between the two owners. The <br />access road and bridge is designed to comply with this agreement. <br />• Water rights are owned and used by the landowner to water stock and irrigate the field west of the San Juan <br />River in the valley floor, and this will continue except for the area used by the access road, which is a <br />permanent feature to remain after mining and reclamation.
