The health of Cape Cod's 890 freshwater ponds is declining due to impacts from stormwater runoff, development, erosion, invasive species, and septic system discharge. Towns and pond advocates are implementing management strategies of different types and scales (watershed level to in-pond approaches) to improve water quality and overall pond health.

Explore the map below to learn about pond-specific challenges, strategies, results and lessons learned to help inform further action across Cape Cod ponds. Updates and additional projects will be added as information becomes available.
