This portion of the East Branch Pecatonica River was evaluated for phosphorus and biology every two years from 2014 to 2018. Phosphorus levels were found to be too high for plant, bug, and fish communities, though bug and fish samples showed them in good condition. This water is on the Restoration Waters list because it is covered by the Dane-Iowa Adaptive Management Plan.
