The
Chagrin River is located in
Northeast Ohio. The
river has two branches, the Aurora Branch and East Branch. Of three hypotheses as to the origin of the name, the most probable is that it is a corruption of the name of a Frenchman, Sieur de Seguin, who established a trading post on the river ca. 1742. The Chagrin River runs through suburban areas of
Greater Cleveland in
Cuyahoga,
Geauga, and
Portage counties, transects two
Cleveland Metroparks reservations, and then meanders into nearby
Lake County before emptying into
Lake Erie.
