The Blanchard River is a approximately 103-mile-long tributary of the Auglaize River flowing through northwestern Ohio. Beginning in central Hardin County, it flows north into eastern Hancock County, then turns sharply west through Findlay before continuing to Ottawa and joining the Auglaize River in western Putnam County. This predominantly rural waterway features numerous bends, riffles, and forested riverbanks, providing anglers with relative isolation and solitude. The river flows through both rural countryside and urban areas, particularly around Findlay, offering diverse fishing environments throughout its course.
