Bear Creek stream flows ceased during the <br />usual mid to late June timeframe. A spike in 2011 total iron levels appeared tied to TSS and <br />seemed "normal" in 2014. A spike in 2012 chloride level occurred for no apparent reason. Some <br />2009, 2010 and 2011 reduced levels of sodium, calcium, conductivity, TDS, and bicarbonate <br />alkalinity appeared to remain at historic levels. The orthophosphate spike remains under the <br />minimal 0.09 mg/l level. Here the importance in the role of the scale of the Y axis seems to <br />predominate. Analysis of the 2017 data, as well as subsidence monitoring and observations in the <br />field, suggests no significant anomalies or any indication of adverse effects attributable to mining <br />activities. <br />8 <br />
