Flow values from the 004 <br /> Pond have been affected by the reduced diameter of the discharge culvert <br /> modified on May 29, 1987 (36 inches to 6 inches). In August 2005, the <br /> discharge culvert wa s replaced with an 8 inch diameter plastic culvert <br /> set approximately one foot above the previous elevation.

It is monitored May through <br />July on a monthly basis. This year, no flow was observed at this site <br />in June or July, although NPDES 004 upstream was flowing continuously. <br />This reduction in flow is due to stream channel infiltration, <br />evapotranspiration, and the absence of lateral inflow from tributaries <br />to Cow Camp Creek. The TDS plot recently reveals a recently decreasing <br />trend. <br />- NPDES Discharge Point 008 (NPDES8) The annual average flow values <br />for the water year since this pond began to flow are: <br />11 <br />
