An additional colluvial well is completed in the <br />colluvium/fill above the Orchard Valley West Mine portal. Plots of <br />the water levels are presented on Figures 22 through 26 and Figure <br />54 and a plot of the field conductivity is presented on Figure 27. <br />Summaries of the of the water quality data for the five wells in <br />the drainage bottoms are presented on Tables 42 through 51. <br />• All of the wells are in the East Roatcap Creek watershed. The <br />wells show a general trend of increasing conductivity from upstream <br />to downstream. The water levels have been declining recently due <br />to the low runoff in 1988 through 1990. The water levels show <br />seasonal variability with levels falling during the late summer and <br />rising during the winter and spring. No impacts related to mining <br />activity were observed. <br />SURFACE WATER <br />Four ponds, two springs, and four surface water stations are <br />monitored in the Roatcap Creek watershed. Summaries and plots of <br />• the data are presented for the four surface water station and two <br /> ponds. Summaries of the discharges from all the ponds and springs <br />
