Notes
List in 2010 due to high fecal coliform and recreational restrictions. More data needed to confirm pollutants leading to degraded habitat. New water quality data reviewed in the 2024 cycle indicated no additional pollutants. In 2026 PFOS contamination was documented and this water was moved from Waters In Restoration List to the Impaired Waters List since there is no TMDL for PFOS. Pollutant
