culvert set approximately one foot above the previous elevation. Review <br />of the TDS plot (SF 0.5) indicates a recently stable trend, with the <br />peak value occurring in September 2005. <br />- Surface Water Site SW -S2 -10 (SSC10) . This site monitors Cow Camp <br />Creek at its confluence with Fish Creek. It is normally monitored in <br />June and July on a monthly basis. However, this year it was sampled in <br />May, and no flow was observed in June or July. This site usually dries <br />up in late summer, although NPDES4 upstream flows continuously. This <br />reduction in flow is due to stream channel infiltration, <br />evapotranspiration and the absence of lateral inflow from tributaries to <br />Cow Camp Creek. The TDS plot reveals a recently decreasing trend. A <br />complete discussion of the impacts to Fish Creek by the Seneca II Mine <br />and the PSCM may be found in this year's Seneca II Mine AHR. <br />Little Grassy Creek Drainage. Two monitoring sites lie within the Little <br />Grassy Creek drainage: SSLG5, located in the upper part of Little Grassy <br />Creek, and NPDES Discharge Point 002, also known as the Wadge <br />Impoundment or Pond 002. <br />- Surface Water Site SW -S2 -5 (SSLG5). Site 5 drains the upper reaches <br />of Little Grassy Creek which are undisturbed by mining. A comparison of <br />its hydrograph to that of NPDES2 indicates that Site 5 is a relatively <br />minor contributor to the flow in this basin. The TDS plot indicates a <br />decreasing trend. <br />- NPDES Discharge Point 002 (NPDES2). Hydrographs are presented in <br />Appendix D. The hydrographs consist of two pages, the first is for data <br />the past two years, and the second shows all historical data. The <br />following table lists the average flow values for each water year. <br />2013 = 0.838 cfs (monthly measurements) <br />2012 = 0.434 cfs " <br />2011 = 2.286 cfs " <br />2010 = 0.460 cfs " <br />2009 = 0.630 cfs " <br />2008 = 1.112 cfs " <br />11 <br />
