Deposits continued to be located using backhoe pits at locations that appeared to be likely deposits. Sometimes it showed good sand, other times it showed nothing. This is very much as it has been in the past. HYDROLOGIC CONDITIONS ENCOUNTERED: No groundwater was encountered in any of the mining pits operated in the past year. Flows in Coal Creek, even during the heavier rain events in the spring of 2010, did not produce significant flows and up until the last inspection no flows occurred. After the inspection there were flash flood warnings along creeks to the south and significant flooding occurred in Elizabeth from Running Creek. No subsequent checks were done at the site to determine whether Coal Creek was impacted by these flows. Excellent moisture has been received over the last 18 months and this appears to have influenced the water table by raising it a significant amount. This is reflected in the quality of the riparian corridor growth and the improved health of the forests. This is probably a result of flows being held back so the drainage occurs more slowly allowing surface flows to percolate into the sands in the riparian corridor and thereby increasing the volume held in the riparian water table. Furthermore, increased vegetation cover on the uplands that feed into the riparian corridor functions to attenuate peak flows so more water is retained on site rather than just running down the stream Status report for 2009 due July 15, 2010 Page 4 of 11
