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. Dissolved oxygen is a concern in this segment.
Trend analyses show a slight improvement in dissolved oxygen levels.
As with other segments in this area, nitrogen levels show a decrease. This decrease is attributed to nitrification processes implemented at wastewater treatment plants. The contact recreation use is not supported because of elevated levels of fecal coliform bacteria. The TDH issued a fish consumption ban due to elevated levels of chlordane found in fish tissue. Echo Lake, another unclassified urban reservoir due to elevated levels of PCBs in fish tissue.
