Review of the TDS plot indicates <br />an increasing trend, although some stabilization appears to have <br />occurred in the past five years. Due to high sediment levels, this pond <br />was dredged out in July and August of this year. <br />- Surface Water Site SW-S2-12 (SSB12). This site monitors Bond Creek at • <br />its confluence with Fish Creek. It is monitored May through September <br />on a monthly basis. This year, flow was present at this site only <br />during the May visit, although NPDES 008 upstream was flowing almost <br />continuously. This reduction in flow is due to stream channel <br />infiltration and evapotranspiration. The TDS plot indicates a slightly <br />increasing trend. <br />- Surface Water Site SW-52-11 (SSF11) This site monitors Fish Creek <br />upstream of its confluence of Cow Camp Creek. It is required to be <br />monitored May through September on a monthly basis, but only if either <br />Sites 10 or 12 are flowing. However, field parameters and flow <br />estimates may sometimes be provided voluntarily when not required. This <br />site is upstream of Seneca II Mine discharges. It was dry in July <br />through September of this year. <br />- Surface Water Site SW-S2-13 (SSF13). This site monitors Fish Creek • <br />downstream of its confluences with Cow Camp Creek and Bond Creek. It is <br />14 <br />
