This report is a water quality assessment of trend data collected at this site between 1986 and 2004. It is noted that there is confirmed increasing trend in boron, calcium, magnesium, sulphate, specific conductivity, and hardness due to acid mine drainage (but are not at levels of concern to aquatic life). Any other values that exceed guidelines are associated with turbidity events and are not biologically significant.
