Watershed Project
The watershed report gives the pond a roadmap.
The 2025 survey identifies runoff and erosion issues across the China, Vassalboro, and Windsor watershed and gives the community practical next steps for protecting water quality.
It is part of a broader Tri-Watershed-Based Management Plan for Threemile, Webber, and Threecornered ponds, a 10-year action plan intended to guide restoration, protection, and future funding.
