• pond is not drained below 6,326 which is the top of the sediment <br />capacity. The water level in the pond has reached up to 6,329 <br />but is being drained when above 6,326. At the time of the high <br />water level in June the Old Mine UG-5 was being drained and pumped <br />non-stop for a couple of weeks. This pumping kept the water level <br />near 6,328 for that period of time. During the Old Mine draining <br />when the pond discharge conductivity increased 4,000, the P-1 <br />increased 370, P-2 dropped 591 and P-3 dropped 456. The water <br />level and conductivity of P-2 and P-3 may be affected by the flow <br />in the diversion SP-A. The Diversion is at 6,340 feet and 50 feet <br />east of P-3. <br />MINE WATER <br />Table M-SS is a listing of monitoring results for the underground <br />sampling. As usual inflows underground are difficult to interpret. <br />The meter on UG-6 operated good this year therefore total discharge <br />of 7.34 MG or an average of 14 c~~ fairly accurate and corresponds <br />• with SP-B discharge. A meter was read on the Old Mine discharges <br />but the rib and floor continually drain proportionally to the water <br />level. The estimated losses around the meter were added to the <br />meter reading to estimate 4.39 MG or 8.4 gpm drained from the Old <br />Mine, UG-5. The water level was 2.3 feet higher at the end of <br />the year than at the beginning which corresponds to 0.75 MG or <br />1.4 gpm. These numbers represent an average inflow into the Old <br />Mine of 9.8 gpm which is lower than the 19.0 gpm estimated for <br />1984 and 14.3 gpm estimated for 1983. Assuming that the Old Mine <br />discharge accounted for 8.4 gpm of the total discharge, the resulting <br />5.6 gpm was all other mine inflows. This 5.6 gpm is lower than <br />the 8.0 ypm estimated for 1984 and the 10.4 gpm estimated for 1983. <br />The flow of UG-1 showed higher than in the past but may have been <br />affected by work recently done along its path. UG-4 was damp but <br />showed no flow. UG-7 had higher flow. The flow from UG-9 continued <br />to be pumped into the Old biine and may have contributed 1/2 gpm. <br />UG-8 was pumping from 7 North and may have contributed 1/2 gpm. <br />• <br />
