Will You Invest in our 3 Rivers?
For 40 years, OARS 3 Rivers has protected and restored the Sudbury, Assabet, and Concord rivers, and we’re just getting started. Everyone who calls the SuAsCo watershed home has a part to play. By partnering with OARS, you help safeguard clean drinking water, healthy habitats, climate resilience, and the beauty and joy of our 3 rivers for generations to come.
Support the Future of Our Rivers

Your gift today fuels the science, restoration, and community programs that keep our 3 rivers healthy and resilient. It supports ecological restoration projects, advocacy for stronger water policies, and hands-on education that connects more people to the water. Together, we can address persistent challenges, including pollution, habitat loss, climate change, and equitable access, while ensuring these waterways remain living treasures for all.
