Prior to <br /> the, pumping periodically increased electroconductivity (EC) in the creek by about <br /> 700 µmhos/cm, causing Fish Creek to occasionally reach the 1500 µmhos/cm <br /> potential material damage threshold for irrigation water in the Fish Creek alluvial <br /> valley floor (AVF). The pumping also caused Trout Creek, below Fish Creek, to <br />P.

The report's graph of Trout Creek's TDS below all mining (site 1005) <br /> shows there is no apparent upward long-term trend in TDS.
