Designated Use Parameter Category Comments

Phosphorus (Total) GoodAquatic Life Sampling data is better than the water quality standards or thresholds for this parameter.

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

Dissolved oxygen satura Good Sampling data commonly meet water quality standards or thresholds for this parameter.

Chlorophyll-a Good Sampling data is better than the water quality standards or thresholds for this parameter.

Escherichia coli Very GoodPrimary Contact Recreation All sampling data meet water quality standards or thresholds for this parameter.

Chlorophyll-a Very Good All sampling data meet water quality standards or thresholds for this parameter.
