The Mahoning River is a river located in northeastern Ohio and a small portion of western Pennsylvania. Flowing primarily through several Ohio counties, it then crosses the state line into Pennsylvania before joining with the Shenango River to form the Beaver River. The Mahoning River drops from 764 feet (233 m) at the headwaters near Winona to 233 feet (71 m) at the outfall near Mahoningtown. It is part of the Ohio River watershed. Source: Wikipedia
