2004. Also affecting discharges from this pond was the pumping of water <br />from this pond for water trucks (last significant amounts were in 2007) <br />and the pumping of water into this pond from the mine water supply well, <br />WTC201 (last significant amounts were in 2000). <br />Review of the TDS plot indicates an increasing trend. Baseline data for <br />this site (WSH6) has been provided in Appendix E1. <br />- Surface Water Site SW-S2W-FG1 (WSHF1). This site is located on <br />Hubberson Gulch downstream of the 006 Gulch confluence. It has been <br />monitored since July 1979. Irrigation ditches were established adjacent <br />this site in July 1999. The TDS plot indicates an increasing trend. <br />However, the peak TDS value occurred in September 2007. Baseline water <br />quality statistics have been provided in Appendix E1. <br />- NPDES 005 (NPDES5). This sediment pond is located in the north mining <br />area on a tributary to Dry Creek referred to as the 005 Gulch. Mining in <br />this basin started in November 1992. Construction of this pond was <br />completed in July 1992 and the first discharge occurred on April 22, <br />1993. This pond wa s dredged in the summers of 1998 and 2001.
