• SURFACE WATER MONITORING <br />Four primary locations and one water-level-only location on Foidel Creek in the <br />vicinity of Mine 1 are monitored. Station 14 is upstream of the effects of all mining <br />activities in the area. USGS Station 09243800 (Station 800) is a short distance <br />downstream of Station 14 and is downstream of the dischazge point for Pond A which <br />captures the drainage from a large azea of spoil springs. Station 8 is a short distance <br />downstream of Mine No. 1 and the Foidel Creek underground mine portal. USGS <br />Station 09243900 (Station 900) is located upstream of the confluence of Foidel and <br />Middle Creeks. Awater-level-only station (304) is located neaz Well 008-AV-2 near <br />the confluence of Foidel and Middle Creeks. <br />Two primary locations on Fish Creek aze monitored. Station 16 which is located <br />immediately downstream of where Fish Creek enters the south end of Twentymile <br />Park. This station has replaced Station 1001 which was located upstream of where Fish <br />Creek enters Twentymile Park. Station 1002 is located on Fish Creek about one-half <br />way through its reach in Twentymile Pazk and downstream of Mine No. 2. One water <br />• level only station (307) is located near We1100frAZ-3. <br />One station on Middle Creek, USGS Station 09423700 (Station 700) located upstream <br />of Mine No. 3, is monitored for flow and water quality. Two locations on Trout Creek <br />aze monitored. Station 69 is located below the confluence with Middle Creek to which <br />Foidel Creek is tributary. Station 301 is located upstream of the confluence of Middle <br />and Trout Creeks. <br />Flows <br />Due to the size of the streams, they must be rated instead of using a more accurate <br />controlled section such as a flume. The USGS maintains continuous recorders at <br />Station 700, 800 and 900. Plots of the historic flow measurements on Foidel Creek are <br />presented on Figures 21 to 27 and Figure 46. Plots of the historic flow measurement <br />on Middle Creek are presented on Figures 28 and 29. Plots of historic flow <br />measurements on Fish Creek aze presented on Figures 30 and 31. Plots of the historic <br />• flow measurements on Trout Creek aze presented on Figures 32 and 33. The flow rate <br />data aze summarized on Table 30. <br />7 - <br />
