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!

RU Preserves Earthworks

Through a 75% match fund from Clean Ohio Fund, Rivers Unlimited along with several other groups, including The Archaeological Conservancy, Heartlands Earthworks Conservancy, Friends of Serpent Mound, South Central Ohio Preservation Society, and 800 individual donors, helped raise funds to purchase The Junction Group, a complex of at least eight earthen structures spanning 20 acres of farmland near Chillicothe, Ohio.

Read an article in American Archaeology about the site and its purchase.
