For the past 250 years, the Concord River has been a witness to American history. On its banks, the first battle of the American Revolution took place. Today, the river and its sister waterways, the Assabet and Sudbury, face another pivotal moment—one that will shape their future.
OARS 3 Rivers is the voice and steward of these historic waterways, working to protect, restore, and expand access to the Sudbury, Assabet, and Concord (SuAsCo) rivers. Founded in 1986 to fight pollution, OARS has become a leader in science-driven conservation, restoration, and public engagement. Once polluted and overgrown with algae, these rivers are now healthier—swimmable in sections, teeming with wildlife, and welcoming to paddlers and anglers.
Yet, the work is far from done. The next chapter in our rivers’ story is about resilience, accessibility, and ensuring their health for future generations.

OARS is expanding Water Wise Workshops, an educational program that has been running since 2004, teaching children about water conservation, river ecosystems, and sustainability through hands-on activities like water quality testing and wildlife identification. Now, with new partnerships in three school districts and over 54 summer camp sessions booked, they aim to engage thousands of young learners annually, deepening their connection to our rivers.
Equally important is getting people on the water. OARS’ new 86 Miles Club challenges paddlers to explore 86 miles of the SuAsCo rivers in honor of its 1986 founding. Its newly launched Concord River Race (May 4, 2025) will unite the community to celebrate river recreation. Meanwhile, their River Recreation Activity Teams will introduce paddling to underserved youth, making river access more inclusive.
Restoring Health & Resilience
Healthy rivers do not happen by accident. OARS’ advocacy has led to significant victories, from securing stricter wastewater regulations to removing outdated dams. Their efforts to restore water quality have transformed the rivers, making sections swimmable and improving habitat for fish and wildlife.
Additionally, their Water Quality Monitoring volunteers play a crucial role in safeguarding river health. Each year, citizen scientists collect vital data that influences environmental policies and conservation efforts.
