Blanchard River Watershed Study

Study Overview

The Blanchard River Watershed Study is authorized by the Water Resources Development Act of 1999, Section 441, Western Lake Erie Basin, Ohio, Indiana, and Michigan.  Section 441 authorizes the U.S. Army Corps of Engineers to '...conduct a study to develop measures to improve flood control, navigation, water quality, recreation, and fish and wildlife habitat in a comprehensive manner...'.  This authority supports a General Investigation/Feasibility Study to assess flood risk management needs and opportunities for the restoration of fish and wildlife habitat within the Western Lake Erie Basin Blanchard River Watershed.


The primary study area is defined as the watershed boundaries of the Blanchard River within Putnam, Hancock, Seneca, Allen, Hardin, and Wyandot Counties in the State of Ohio.  The study area will encompass the entire Blanchard River Watershed including upstream areas, which contribute to flooding, and downstream areas to the confluence of the Blanchard River and the Auglaize River.


The watershed is approximately 771 square miles.  Frequent flooding has impacted the quality of life in the watershed and hindered economic development efforts.  The study will provide a framework to support sustainable development in the watershed.
