Your Contribution:

Funds collected here will be used 100% to support the research, restoration, and preservation of Winthrop Lake, one of Holliston’s most valuable natural resources.

Your Impact this year:

Thanks to the extraordinary generosity of our community, Friends of Winthrop Lake successfully leveraged 2025 contributions to form a public-private partnership (PPP) with the town of Holliston allowing us to take our first step to improving the lake, hiring an independent environmental engineering firm to carry out a complete lake health assessment. Your donations served as the necessary matching funds for a significant grant we were awarded.  This is a powerful example of how your support directly translates into tangible action for the future health of the lake
