Phosphorus (Total) Slightly BadAquatic Life Data exceed water quality standards or thresholds for a given parameter by a small margin.

pH Slightly Bad Data periodically exceed water quality standards or thresholds for a given parameter by a small margin.

Oxygen, Dissolved Encouraging Limited data for this parameter predicts water quality standards or thresholds are being met; however more data are

necessary to fully assess the parameter.
