The Shenango rises in west-central Crawford County ^[1] and initially flows northwestwardly into the Pymatuning Reservoir, which was formed in 1932 by the construction of a dam on the river.^[3] The lake turns to the south, widening into Ashtabula County, Ohio, and passing through Pymatuning State Park.^[2] Below the dam and after returning fully to Pennsylvania, the Shenango flows south-southeastwardly into Mercer County, passing Jamestown and Greenville before turning westwardly into Shenango River Lake,^[2] formed in 1965 by a U.S. Army Corps of Engineers dam ^[4]. Below that dam, the Shenango flows southwestwardly through the communities of Sharpsville and Sharon (near which it briefly enters Trumbull County, Ohio); then south-southeastwardly past Farrell, Wheatland and West Middlesex into Lawrence County, where it passes New Castle and Oakland.^[2] It joins the Mahoning River to form the Beaver River, 3 mi (4.8 km) southwest of New Castle.^[1] Crawford County is a county located in the state of Pennsylvania. ...
