18. Basin Summary Report Format • Watershed Overview • Segments and Assessment Units • Active Wastewater Permits • Permit Numbers • Discharge Information

19. Basin Summary Report Format Cont. • Sampling History • All stations throughout history • Current Stations • 2008 Monitoring Stations • Entity • Frequency • Parameter Groups

20. Basin Summary Report Format Cont. • Flow Information

21. Basin Summary Report Format Cont. • 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) 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.
