At the Seneca II Mine, there are eight spoil springs are monitored for field parameters and full-suite lab samples in the spring and fall seasons. In addition, Spoils Spring 1 was sampled for a full-suite lab samples concurrently with NPDES 004, and was monitored monthly and concurrently with NPDES 004 for field parameters from March to October. 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, a TDS regression plot using the LOWESS method (see Ground Water Quality section), and then a listing of historic percent milliequivalent: values for major ions and TDS values. Crest stage gage rating curves are presented in Appendix E. Lab samples are handled identically to procedures discussed previously in the Ground Water Quality section. For the sake of brevity, the prefix that precedes- allsur.face water site names will often be dropped throughout the following text. As an example, Site SSLGS will be referred to as Site 5.. Fish Creek Drainage. Six monitoring sites exist within the Fish Creek drainage: NPDES 004 and Site 10 are located on Cow Camp Creek. NPDES 008 and Site 12 are located on Bond Creek. Sites 11 and 13 exist on Fish 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 yearly average flow values since this pond began to flow are: 2001WY (Water Year) = 0.147 cfs (monthly measurements) C~ • ZOOOWY = 0.147 cfs ' 1999WY = 0.240 cfs (monthly measurements winter, weekly rest of year) . 1998WY = 0.468 cfs " 12
