2.0 STUDY CONCLUSIONS <br />2.1. PUMPING CONDITIONS <br />Pumping conditions will lower the local water table in the lower gravel aquifer <br />during the life of the mining operation as shown in Sheet -3. The are no <br />permitted wells in the area influenced by the cone of depression. <br />2.2. RECLAMATION <br />The reclamation perimeter drain was designed to minimize the potential for any <br />increase in groundwater table elevations. Depression of the water table is <br />expected to occur down-gradient of the lined pit on the order of 4-5 ft locally. <br />There are no permitted wells in this area. <br />2.3. SEEPAGE FROM BOULDER-WELD CANAL <br />As discussed above, the canal seepage is captured by a drain just north of the <br />proposed pit. Pumping conditions had no appreciable impact on the canal <br />seepage or drain flows. The gravel operation is therefore predicted to have no <br />effect on canal seepage, on canal flow or water table elevations in the upper <br />aquifer (upper sandy silt layer). <br />File Pit 112 <br />Groundwater Modeling Report <br />6of6 <br />
