Mercer County has two rivers running through it; the Wabash and the St. Marys. The Wabash watershed is part of the Gulf of Mexico's watershed. The St. Marys watershed is part of Lake Erie's watershed. Creeks between these two watersheds are within a mile of each other at some places in Mercer County. This area/line that divides the drainage basins is known as the St. Lawrence Continental Divide.
The Miami & Erie Canal was significant in the development of Ohio as settlers found an easier way into the wilderness and commerce found a cheaper route to markets. Beginning in 1825, it took 20 years to construct the 249 miles of canal from Cincinnati to Toledo and cost more than $8 million.A great place to begin local exploration of the canal is the Miami & Erie Canal Visitors Center at Lock One in New Bremen in nearby Auglaize County.
Families have long enjoyed vacationing at beautiful Grand Lake St. Marys. Ohio's largest inland lake has been a destination for boating, swimming, fishing and picnicking for many generations. Grand Lake St. Marys State Park consists of nearly 600 acres of prime lakeside parkland.
