Ken' Coal - 2004 Annual Hydrology Report February, 2005 <br />6.0 MINE AREA SURFACE WATER <br />The sediment ponds (Stations 301, 302, 303, 304, 305, and 321) were monitored weekly from Mazch through <br />June and montlily during the remaining months through September, 2004. There was some inflow from <br />snowmelt in Mazch but no outflows. There were no outflows observed in any of the months during this <br />monitoring period. With slightly below average snow pack and minor spring precipitation, all ponds partially <br />filled during April and May. Most of the ponds retained some water through October, except for the ponds <br />associated with Stations 303 and 321, which were dry by July. Due to the no-flow conditions, no field <br />parameters were measured during the 2004 water yeaz and no additional sampling was conducted. The <br />recorded measurements and field observations aze contained on the field data logs in Appendix A, 2004 Field <br />Data. <br />Surface water sites 300, 306, 322, and 327 were dropped from monitoring as of January 1999 and Station 314 <br />was eliminated from the monitoring program in October 1999. No data was collected from any of these sites <br />during the 2004 water yeaz. <br />
