The timing of when <br />flow values are collected affects these averages. Flow values from Pond <br />004 have also been affected by the reduced diameter of the discharge <br />culvert modified on May 29, 1987 (36 inches to 6 inches). In August <br />2005, the discharge culvert was replaced with an 8 inch diameter plastic <br />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 monitored in June and <br />July on a monthly basis. This site usually dries up in late summer, <br />although NPDES4 upstream flows continuously. This reduction in flow is <br />10 <br />
