About the blanchard river

The Blanchard River is a 102.1-mile-long river in Ohio. The river's drainage basin covers about 1,219 square miles, including parts of Hancock, Hardin, Putnam, and Allen counties. The Blanchard River Watershed has a long history of flooding, causing significant damages to agricultural land and residential properties. To mitigate flood damages, several flood-control measures were constructed, including the Ottawa River Reservoir, Eagle Creek Dam, and Blanchard River Dam. These projects help to reduce flood damages in the region. Additionally, the Blanchard River supports agricultural uses, including crop irrigation and livestock watering, and recreational uses, such as fishing and boating.
