temperature, pH, and electrical conductivity) and NPDES lab parameters. Stream Monitoring Sites SSG1, SSG2 and SSLG5 are sampled three times a year for field parameters and full -suite water quality. The first sample of the year is collected during the spring runoff (March or April), the second sample is collected after the spring runoff (May or June), and the third sample is collected during base flow conditions (September). Lab samples collected at all these sites were analyzed using the surface water parameter lists shown on Table 9 and 9A. At the PSCM, there are eight spoil springs that are monitored for field parameters and lab samples in the spring season. Surface water quality data are presented in Appendix D. Data for each site begins with a flow hydrograph of all historic data (plus an annual hydrograph for NPDES sites), followed by a listing of individual water quality and quantity data for the current water year, remarks and a TDS regression plot using the LOWESS method (see Ground Water Quality section). Lab samples are handled identically to procedures discussed previously in the Ground Water Quality section. For the sake of brevity, the prefix that precedes all surface water site names will often be dropped throughout the following text. As an example, Site SSLG5 may be referred to as Site 5. Fish Creek Drainage Two PSCM monitoring sites exist within the Fish Creek drainage: NPDES4 (aka, Pond 004) and SSC10 are located on lower Cow Camp Creek. - NPDES Discharge Point 004 (NPDES4). Hydrographs are presented in Appendix D. The hydrographs for NPDES sites consist of two parts; the first being data for this year only, while the second shows all historical data. The water year average flow values since this pond began to flow are: 2011 = 0.498 cfs (monthly measurements) 2010 = 0.132 cfs " 2009 � 0.146 cfs if 0
