i • <br />constant from late Aueust to early November, with a flow of 13.3 <br />gpm. The flow increased to 24.8 gpm in mid-November and decreased <br />i <br />to 18.8 gpm in the=_ late part of November and early part of <br />Der_ember. <br />NPDES site 002~(No Name Gulch) recorded a high flow of 445.1 <br />gpm and overall average flow of 85.7 gpm during the period (Figure <br />C-2). The high flow observed was most likely due to snow melt or <br />D-pit pumping during! the last part of February and the first part <br />of March. Discharges varied throughout the period, showing some <br />of the variability that can be attributed to the precipitation <br />events. <br />The Coyote Dam Seep, below NPDES site 0~5, showed a constant <br />discharge of 4.7 gpm from July 1 through October 19 until the • <br />rer_order was pulled (Figure C-3). <br />Flow data recorded for NPDES site m03 (East Buzzard Gulch) <br />from mid-July to mid-August documents no flow during this period. <br />NPDES site 4JPJ6 (W. Buzzard Gulch) recorded a high flow of <br />379.1 gpm during 1991. Figure C-4 presents the flows versus time. <br />Low flows dominate the plot with an average flow during the period <br />of 7.4 gpm. Flow at the 10YR/24HR flume Coyote site was not <br />observed during 199]. after Spring melt-out. <br />• <br />4_2 <br />
