<br />i~ <br /> <br />These are high - 1?00 mg/1 or greater -but they occur before irrigation season. Later in the season, <br />virtually independent of streamflow volume, the TDS diminishes to 5~0 mg/l or less. This is a very <br />interesting effect. The "Flushing" effect during the spring snowmelt seems to even outweigh the <br />effect of dilution from higher instream flows. This is seen with high TDS in the spring when the <br />stream flow is higher than later in the summer. So spoil spring contribution apparently reaches a <br />maximum at the same time as run-off. In the final analysis, the mine stays within the PHC <br />predictions very nicely. <br />C~-~ t s i~ a ~a-w --~1~,, Cc~,~73~x~ <br />re - ~o~wwt.e.l-~. ~ ~ 3 ~e -~ -~L <br />~'1~ ~- .Q,~PNaq~"fi~ p~,a- S o ~ -~ 1 YD v~" <br />~~~ ~vatr~-S~ , <br />
