• <br />TERROR CREEK <br />COLLUVIAL WELLS <br />One colluvial well is completed in Terror Creek colluvium. A plot <br />of the water levels and conductivity is presented in Figure 32. <br />Summaries of the water quality data for the well are presented in <br />Tables 68 and 69. <br />The water level in Well SM-4 shows a pattern similar to other <br />colluvial wells. Levels appear to have stabilized following a <br />decline due to the low runoff in 1988 through 1990. The water <br />level shows seasonal variability which was on the order of 8 to 13 <br />• feet during the higher snow fall years of 1986 and 1987 but less <br />than 5 feet in the other years. The seasonal fluctuations follow <br />the expected pattern with levels falling during the late summer and <br />rising during the winter and spring. <br />The well is not located near recent mining and no impacts related <br />to mining activity were expected or observed. <br />SURFACE WATER <br />Two ponds, seventeen springs, and four surface water station are <br />monitored in the Terror Creek Drainage. Summaries and plots of the <br />data are presented for the four surface water station and ten <br />. springs. Plots of the flow rate and conductivity data are <br /> presented in Figures 33 through 44. Summaries of the flow rate <br />11 <br />
