Our mission is to restore, maintain and improve Ohio's rivers and streams, their water quality, scenic beauty, their multiple economic uses, and their effect upon Ohio's quality of life.

Rivers Unlimited accomplishes this mission by engaging citizens and organizations in direct action such as water quality monitoring, stream cleanups, and influencing public policy at the local, state, and national levels.

Volunteers are essential to RU success. Volunteering across all of our programs is an enjoyable and rewarding experience. Join us for our next water quality monitoring or stream cleanup and see for yourself.

Rivers Unlimited's most important asset is our people. Become a member today!
