Today’s popular recreation area formed as a result of the last ice age. The name Portage Lakes comes from an old Indian portage path that connected the Cuyahoga River flowing north to Lake Erie and the Tuscarawas River, a tributary of the Muskingum River, which flows south to the Ohio River. This proved advantageous for Indians and early settlers as navigation from Lake Erie to the Ohio was possible with only an eight-mile portage.
