Groundwater Baseline Information <br />Springs in the unnamed channel <br />It is expected that the operation will be a dry mining operation since it will operate on the second <br />terrace above the Eagle River. A few springs, however, have been found in the unnamed drainage <br />which flow directly in response to flows from the Stremme and Gates irrigation ditch.. This ditch is <br />located approximately 1/3 mile to the south of the permit area. Map Exhibit C-2 shows the location <br />of the springs in the unnamed drainage. Site investigations conducted on April 16, 1996 showed no <br />spring flows to the unnamed drainage, it is believed that the flows are caused by irrigation seepage <br />from the Stremme Gates ditch located uphill and south of the property. The flows seem to take <br />place only when the irrigation water is running and seem to vary from 2 to 20 gallons per minute. <br />Flows were seen in the drainage during the stunmer of 1996 and during inspections in September. If <br />the flows were the result of natural springs, the April 1996 site investigation would have likely <br />shown flows, when groundwater levels are usually at their highest. No flows or wet conditions of <br />any kind were found at that time. The seepage likely enters the porous gravel zone and travels <br />along the top of the less permeable shale zone immediately below the gravel until the surface is <br />encountered near the outlet of the springs. It is possible that the springs are shallow and may be <br />encountered during excavation of the pit area on the south side of the property. Water quality <br />appears similar to that of the surface water flows in the area, with pH slightly above 7 and relatively <br />high dissolved solids, but adequate for livestock and irrigation use. This also supports the notion <br />that the flows are coming from the Stremme & Gates ditch since this water is taken directly from <br />the Eagle River, which has similar quality. <br />Carol Ann Permit CDMG Application <br />37 <br />
