Richard D. Piland & Associates <br />Hydrology Monitoring Report 2007 <br />is <br />MIDDLE FORK AND DAVIS GULCH DAM MONITORING <br />The Middle Fork Dam has three clusters of piezometer tubes: referenced as <br />East, Middle and West. Water levels in the piezometers are measured quarterly along <br />with the reservoir water level. Table 9 lists the reading for 2007. The reservoir level <br />was fairly consistent at around the 7462 elevation during the year. Piezometer levels <br />did not fluctuate as much as past years. <br />The Middle Fork and Davis Gulch dams have seepage water measuring devices <br />in place. They are read monthly. Table 10 lists the readings for 2007 at both sites. <br />Seepage flows showed a increase during snow melt. Graphs of the Dam Monitoring <br />Data appear in Appendix E of this report. A timed bucket measurement was made at <br />the effluent seepage for the gallons per minute reading. <br />NPDES SETTLING POND #5 DISCHARGE <br />Settling Pond #5 did not discharge into Parachute Creek during the 2007 Water <br />Year. No water quality samples were collected. <br />ESR SURFACE WATER DISCHARGE • <br />The ESR Flume did not discharge during the 2007 Water Year. The snow melt <br />runoff did not produce a discharge. <br />12 0
