It happens every year up and down the Ohio River bank. People volunteer their time to keep the river clean.
This year more than 100 people started at Point Park and worked their way up bank gathering trash.
Dupont Washington Works has sponsored the sweep for 15 years. Representatives say this clean up is important for the river and the community.
"The river belongs to all of us and you can't overemphasize the importance and the need to keep that resource as an asset to our community," says Dupont Washington Works Public Affairs Consultant Robin Ollis-Stemple.
The Parkersburg Yacht Club volunteered boats in the cleanup and some local boy scouts gave their time.
Organizers say there wasn't as much small trash this year, but they threw away big items like mattresses and tires.
