Water Quality Analysis and Trend Analysis  TDS, chloride, sulfate for entire segment  Analysis for each AU (min, max, median, discussion)  DO  pH  Ammonia  Nitrate+Nitrite  OP  Total Phosphorus  Chlorophyll a  TSS  Bacteria (E.Coli, Enterococcus) Basin Summary Report Format Cont. pH (su): 58 samples, ranging from 7.5 to 8.6, median value is 7.8, 0 values outside criteria range of 6.5 to 9, decreasing trend. There is a fairly large variation in pH values, but it does not seem to correlate with seasons or changes in flow. The data indicates a decreasing trend. The values are still well above the minimum criteria value and are not a concern at this time. However, this parameter needs to be watched and understood so that it does not become a problem.
