Alan affecting flow from the 004 pond is the <br />reduced diameter of the discharge culvert modified on Hay 29, 1987 (36 inches to 6 <br />inches). <br />Review of the TDS plot indica tea that 1DS values have consistently increased since 1982, <br />primarily due to a concurrent. increase in upgradient mined area and ground. water <br />resaturation in the spoils. However, some stabili Bing of TDS values may be occurring. • <br />- Surface Water Site SW-S2-10 (SSC10). The site monitors Cox Camp Creek at its confluence <br />with Fish Creek. It ie monitored May through September on a monthly basis. This year, no <br />flow was present at this site. on the Suly, August, and September monthly visits, although <br />NPDES 004 was Flowing continuously those months. This reduction in flow is due to stream <br />channel infiltration, evapotranspiration, and the absence of lateral inflow from <br />tributaries to Cow Camp Creek. The TDS plot reveals an increasing trend. <br />- NPDES Discharge Point 008. the annual average flaw (from weekly measurements, for the <br />water year) since this pond began to flow are: <br />1999 = 0.246 cfs <br />1998 = 0.473 cfs <br />1997 = 0.606 cfs <br />1996 = 0.479 cfs <br />1995 = 0.337 cfs <br />1994 = 0.157 cfs <br />1993 <br />1 = 0.332 cfs • <br />992 = 0.132 cfs <br />)2 <br />
