Eagle Park Reservoir III 'llllll <br /> Final Analytical Summary IIIIII�II <br /> October 29, 1997 <br /> 999 <br /> Robinson Seepwater Collection System <br /> Ground Water <br /> Ground water at the toe of Robinson Lake Reservoir is captured by an approved 1996 <br /> Environmental Protection Facility known as the Robinson Seep Cut-off Wall. Stormwater <br /> diversion to reduce the volume of water entering the process area during spring runoff was <br /> implemented in September 1997 on the east side of the cut-off wall. On the west side of the cut- <br /> off wall, cursory drainage control has been implemented and will be managed according to the <br /> objectives of the Climax Mine Stormwater Management Plan (see attached diagram). The top of <br /> the cut-off wall was also exposed in an effort to verify that flow is not going over the top of the <br /> wall. Due to the large volume of runoff, estimated at six (6) acre-feet, that will occur in the Spring, <br /> a capture basin was excavated up stream of the cut-off wall. This will provide an estimated 0.5 <br /> acre-feet of storage during heavy runoff. <br /> A certification is attached for the alternative offset water level probe installed as a modification to <br /> this Environmental Protection Facility. This installation was described to the Division in a letter <br /> dated April 9, 1997 <br />
