About the mahoning river

The Mahoning River is a 113-mile-long river in Ohio, running through the cities of Youngstown, Warren, and Newton Falls. The river has a long history of pollution due to the steel and coal industries that once dominated the area. However, recent efforts have been made to clean up the river and improve water quality. The Mahoning River watershed includes several reservoirs, including the Berlin Lake Reservoir, which provides water for drinking and agriculture. Additionally, there are several dams along the river, including the Warren Dam and the B&O Railroad Dam. Despite its past pollution, the Mahoning River is now used for recreational activities, such as fishing and boating, and supports agricultural practices in the surrounding areas.
