Surface Water Site SW -S2-10 (SSC10). <br />This site monitors Cow Camp Creek below Pond 004 at its confluence with <br />Fish Creek. It is normally monitored in June and July. This year it was <br />sampled in April and June. This site usually dries up in late summer, <br />although NPDES4 upstream flows continuously. The reduction in flow is <br />due to stream channel infiltration, evapotranspiration and the absence <br />of lateral inflow from tributaries to Cow Camp Creek. The TDS plot <br />reveals an increasing trend. <br />Little Grassy Creek Drainage. <br />Two monitoring sites lie within the Little Grassy Creek drainage: SSLG5, <br />located in the upper part of Little Grassy Creek, and NPDES Discharge <br />Point 002, also known as the Wadge Impoundment or Pond 002. <br />Surface Water Site SW -S2-5 (SSLG5). <br />Site 5 drains the upper reaches of Little Grassy Creek which are <br />undisturbed by mining. A comparison of its hydrograph to that of NPDES2 <br />indicates that Site 5 is a relatively minor contributor to the flow in <br />this basin. The TDS plot indicates an increasing trend. This site is <br />normally monitored in April, June and September. No flow was observed <br />in June and September of this year. <br />NPDES Discharge Point 002 (NPDES2). <br />The following table lists the average flow values for each water year. <br />2017 <br />= 0.258 <br />cfs (monthly measurements) <br />2016 <br />= 0.670 <br />cfs " <br />2015 <br />= 0.432 <br />cfs " <br />2014 <br />= 0.713 <br />cfs " <br />2013 <br />= 0.838 <br />cfs <br />2012 <br />= 0.434 <br />cfs " <br />2011 <br />= 2.286 <br />cfs " <br />2010 <br />= 0.460 <br />cfs " <br />2009 <br />= 0.630 <br />cfs " <br />2008 <br />= 1.112 <br />cfs " <br />11 <br />
