Water is impaired due to one or more pollutants and associated quality impacts.
Notes
This portion of the West Branch Sugar River was evaluated for phosphorus, bugs, or fish every two years between 2012 and 2020. Phosphorus levels were too high for healthy aquatic communities like plants, bugs, and fish. Poor bug community health was found in 2020. Elevated temperature was identified in the 2024 cycle.Pollutant
