Mercer County consists of 100 small watersheds that make up the Ohio River and Allegheny sub-basins. They range in size from 1.75 acres to over 31,000 acres. The Ohio River and Allegheny sub-basins drain 364,596 acres and 71,867 acres respectively in Mercer County. Within the Ohio River sub-basin is most notably the Shenango River Watershed.
