• April 13, 1991 <br />Page 3 <br />STEVEN'S GULCH <br />COLLUVIAL WELLS <br />Five colluvial wells are completed in Steven's Gulch colluvium. <br />Plots of the water levels are presented on Figures 3 through 7 and <br />a plot of the field conductivity is presented on Figure 8. <br />Summaries of the of the water quality data for the five wells are <br />presented on Tables 6 through 15. <br />The data from the wells show a general trend of increasing <br />conductivity from upstream to downstream. The water levels have <br />• been declining recently due to the low runoff in 1988 through 1990. <br />The water levels show seasonal variability with levels falling <br />during the late summer and rising during the winter and spring. <br />No impacts related to mining activity were observed. <br />SURFACE WATER <br />Fourteen ponds, thirteen springs, and one surface water station are <br />monitored in Steven's Gulch. Summaries and plots of the data are <br />presented for the one surface water station, five ponds, and seven <br />springs. Summaries of the discharges from all the ponds and <br />springs are presented on Tables 109 and 110. Plots of the flow <br />• rate and conductivity data are presented on Figures 9 through 21. <br /> A summary of the flow rate date for station SW-5 is presented on <br />
