The Little Cuyahoga River is Cascade Valley Neighborhood’s most important natural asset. It is a 17.4-mile-long tributary to the Cuyahoga River. The origin of the name “Cuyahoga” is Native American, meaning "crooked river." It is located in southeast Summit County and southwest Portage County.
The Little Cuyahoga Watershed is a 61.7 square mile area and drains portions of the City of Akron, City of Tallmadge, Springfield Township, Village of Lakemore, Village of Mogadore, Brimfield Township, Suffield Township, and Randolph Township.
The Little Cuyahoga River is an urban stream currently not meeting state water quality standards for biological and recreational uses. The overriding reason for poor water quality was the combined sewer overflows (CSOs) from the City of Akron.
