Contact recreation use is not supported because of elevated fecal coliform bacteria levels. A concern for dissolved oxygen exists. The dissolved oxygen and nitrogen levels in this segment have improved due to improvements in wastewater treatment. Some evidence shows measured concentrations of nitrogen are increasing. This may be attributed to the nitrification process now employed by wastewater treatment facilities.
Stream flow is dominated by domestic wastewater effluent.
Water quality historically has been poor, but improvement in wastewater treatment levels has resulted in measurable improvements in water quality. Low levels of dissolved oxygen are no longer a concern in this segment. Contact recreation use is not supported because of elevated levels of fecal coliform bacteria. Elevated nutrients continue to be possible concerns, with decreasing trends in levels of ammonia nitrogen and slightly increasing trends in other forms of nitrogen as well as phosphorus. Documented water quality improvements in the segment are attributed to improvements to wastewater treatment levels implemented by major dischargers in the area.
