However, soma stabilizing of TDS <br />values appears to be occurring in the lnst two years. <br />- Surface water Site Sw-S2-10 (S3C10). This site monitors Cow Camp Creek at its <br />i confluence with Fish Creek. It is monitored May through September on a monthly <br />basis. This year, flow was present at this site only during the May monthly <br />visit, although NPD89 004 upstream was flowing continuously. This reduction is <br />flow La due to stream channel infiltration, evapotranepiratioa, and the absence <br />of lateral inflow from tributaries to Cow Comp Creek. The TDS plot reveals an <br />increasing trend. <br />- NPDEB Discharge Point 008 (NPD838).
