The Linesville Spillway sits just east of the Pennsylvania-Ohio border in the northern portions of the state. It is in the 16,893-acre Pymatuning State Park.
Pymatuning State Park is one of the biggest state parks in all of Pennsylvania. It’s also home to Pymatuning Reservoir, a 17,088-acre lake that’s the largest one in the state.
The spillway regulates the flow of the Shenango and Beaver Rivers. However, the design of the spillway results in an increased number of fish food flowing into the area.
Visit the Fish Hatchery and Visitor CenterYou’ll find earthen ponds, exterior concrete raceways, and a hatchery building with stainless steel and concrete raceways.
