Notes
Stony Brook was assessed in 2016 and 2018 for temperature and levels were good for healthy aquatic communities. In 2020 Stony Brook was assessed for phosphorus and levels were found to be too high for healthy aquatic communities like plants, fish, and bugs. This water was listed in 2020. This listing is covered by the Northeast Lakeshore TMDL, approved in 2023. New water quality data reviewed in the 2024 cycle confirmed the phosphorus listing.Pollutant
