Station 14 is upstream of the effects <br />of all mining activities in the area. USGS Station 09243800 (Station 800) <br />is a short distance downstream of Station 14 and the unnamed tributary and <br />is downstream of a large area of spoil springs. Station 8 is a short <br />distance downstream of Mine No. 1. Water quality samples are collected <br />upstream of the nitrate loadout out and flow readings are taken downstream <br />of the nitrate loadout. USGS Station 09243900 (Station 900) is located <br />upstream of the confluence of Foidel and Middle Creeks. A water level only <br />station (304) is located near Well 008-AV-2. Two primary locations on Fish <br />Creek are monitored. Station 1001 was located upstream of where Fish Creek <br />enters Twentymile Park. It has been replaced by Station 16 which is located <br />immediately downstream of where Fish Creek enters the south end of <br />Twentymile Park. Station 1002 is located on Fish Creek about one-half way <br />through its reach in Twentymile Park and downstream of Mine No. 2. One <br />water level only station (307) is located near Well 006-AZ-3. One station <br />on Middle Creek is monitored. It is located upstream of Mine No. 3 and USGS <br />Station 09423700 (Station 700). Two locations on Trout Creek are <br />monitored. Station 69 is located below the confluence with Middle Creek to <br />which Foidel Creek is tributary. Station 301 is located upstream of the <br />confluence of Middle and Trout Creeks. <br />Flows - <br />Due to the size of the streams, they must be rated instead of using a more <br />' accurate controlled section such as a flume. The USGS maintains continuous <br />recorders at Stations 700 to 800 and 900. Plots of the historic flow <br />' measurements on Foidel Creek are presented on Figures 21 to 27 and Figure <br />45. Plots of the Historic flow measurement on Middle Creek are presented on <br />t Figures 28 and 29. Plots of historic flow measurements on Fish Creek are <br />presented on Figures 30 and 31. Plots of the historic flow measurements on <br />Trout Creek are presented on Figures 32 and 33. The flow rate data is <br />' summarized on Table 30. The data shows the typical seasonal <br /> <br />' - 6 - <br />
