Cavanaugh (Sunset) Pond
About Cavanaugh Lake (Sunset Pond)
Cavanaugh Pond (also known as Sunset Hills Pond) is a small, shallow lake in southeastern Plymouth, just north of Sunset Hill Elementary School. The lake has a relatively small drainage area of 126 acres which includes 3.6 acres of high quality wetlands. Water quality appeared to be improving in the mid 1990’s. BCWMC monitoring in 2019 shows the lake has good water quality and a nice native plant community. A small patch of the aquatic invasive species, curly-leaf pondweed was identified in 2019 and will be closely monitored by volunteers on the lake to ensure it doesn't begin impacting native plant communities.
