samples. When no flow is observed at the Cou Camp or Bond Creek sites (Sites 11 and 131, <br />' • the two Fish Creek sites (Sites 10 and 12) are not monitored. <br /> <br />At the Seneca II Mine, there axe eight spoil springs axe monitored for field parameters <br />and full-suite lab samples in the spring and fall seasons. In addition, Spoils Spring 1 <br />was sampled for a full-suite lab samples concurrently with NPDES 009, and was monitored <br />twice monthly and concurrently with NPDES 009 for field parameters from March to May. <br />Surface water quality data are presented in Appendix D. Data for each site begins with a <br />flow hydrograph of all historic data (plus an annual hydrograph for NPDES sites), followed <br />by a listing of individual water quality and quantity data for the current water year, a <br />TDS regression plot using the LOWESS method (see Cround Water Quality section), and then a <br />listing of historic percent milliequivalent values for major ions and TDS values. Crest <br />stage gage rating curves are presented in Appendix E. Lab samples are handled identically <br />to procedures discussed previously in the Cround Water Quality section. For the sake of <br />brevity, the prefix that precedes all surface water site names will often be dropped <br />throughov t'the following text. As an example, Site SSLGS will be referred to as Site 5. <br />• Fiah Creek Drainage. Six monitoring eitea exist within the Fiah Creek drainage: NPDES 009 <br />and Site 10 are located on Cow Camp Creek. NPDES 008 and Site 12 are located on Bond <br />Creek. Sites 11 and 13 exist on Fieh Creek. <br />- NPDES Discharge Point 009 (NPDE 59) Hydrograph9 based on weekly flow measurements are <br />presented in Appendix D. The hydrographs for NPDES aitae consist of txo parts; the first <br />being data fox this year only, while the second shows all historical data. <br />The yearly average flow Ifrom weekly measurements) since this pond Degan to flow were <br />1999wY (water Year) = 0 .240 cfs <br />1998WY = 0 .468 cfs <br />1997WY = 0 .506 cfs <br />1996WY = 0. 609 cfs <br />1995WY = 0.357 cfs <br />1994wY = 0.121 cfs <br />1993WY = 0.360 cfs <br />• 1992wY = 0.131 cfs <br />1991WY = 0.189 cfs <br />
