Swimming Safety
Grade onlyBacteria advisory
Based on clarity and algae grades from past sampling — we do not hold live water temperature and a current cyanobacteria reading for this lake. Check your state or county health department before you swim.
The D is nutrients and algae, not a swimming clearance. Pequot Pond is listed impaired under Clean Water Act §303(d) (IR 5) for algal growth, noxious aquatic plants, nuisance exotic species, nutrients (phosphorus, nitrogen), oxygen depletion (low DO), pathogens (E. coli, fecal). Check local advisories before you swim.
Water Quality Grade: D (Nutrient-rich)

Depth marked “est.” is a modeled maximum from GLOBathy (Khazaei et al. 2022, CC0), not a measured survey. Massachusetts has not published bathymetry for Pequot Pond.
Lake Size & Watershed
Size, shoreline, and watershed area from HydroLAKES (HydroSHEDS). Mean depth here is modelled, not surveyed — HydroLAKES v1.0 estimates lake depth from surrounding terrain rather than from soundings. Treat it as an approximation, and prefer a state bathymetric survey where one exists.
