The stream flow data shows the typical seasonal variation with a rapid rise and fall of flow rates <br />during Spring runoff. Flows for Sites 16, 69, 1001, 8, 1002, and 1003 are not measured during <br />the winter due to the streams being frozen. Station 14 on Foidel Creek often did not record Flow <br />in the creek during the fall, winter and summer because it is located near the top of the <br />drainage. Foidel Creek tows tend to be maintained nearly year-round by discharges from [he <br />spoil springs feeding the sediment ponds. <br />The data indicates a fairly good correlation between upstream and downstream stations on each <br />stream. As expected the upstream stations generally had a lower Clow than the downstream <br />stations on each stream. On Trout Creek the downstream station has a lower flow than the <br />upstream station, probably due to irrigation withdrawals. <br />Water Quality <br />• Water quality samples are collected at all the primary sites on a regular basis. The water quality <br />summaries are presented on Tables 31 through 48. Plots of historic water quality data for Foidel <br />Creek are presented on Figures 34 through 37, Figure 50 and Figure 53. A plot of historic <br />water quality data for Fish Creek is presented on Figure 38. A plot of water quality data for <br />Middle Creek is presented on Figure 39. Plots of historic water quality data for Trout Creek <br />are presented on Figures 40 and 4l. <br />The base level of field conductivity measured during spring runoff, was higher in the <br />downstream sites on Foidel Creek. It is approximately 750 umhos/cm in the upstream site (14) <br />and from 1500 to 1800 umhos/cm in the downstream sites (800 and 8). Since 1981 the base <br />level for conductivity at both downstream sites has been increasing although there appears to <br />have been alevelling-off since 1989. The upstream site has also shown an increasing trend in <br />conductivity since 1986, presumably as a result of lower runoff flows since this time. During <br />the 1992 irrigation season, the field conductivities at Station 14 could not be measured as there <br />was no measurable Flows at this station during this time. The field conductivity at Station 8 was <br />• approximately 3300 umhos/cm. <br />-8- <br />
