July 2009 Watershed TMDL Report

What are the essential facts?  Ohio EPA studied the Blanchard River watershed and found water quality problems at all of the locations measured.  The watershed can make progress towards restoration with practical, economical actions.  Improving the streams depends on the participation of the watershed’s residents.

What is the significance of this report? The Blanchard River Watershed TMDL Report is a tool that will include local ideas from the endorsed watershed action plan to help improve and maintain water quality and habitat in the watershed.

What is a watershed? A watershed is the land area from which surface runoff drains into a specific body of water.

Overall, the land use in the Blanchard River watershed is 81 percent row crop, 10 percent developed urban/residential, 6 percent forest, 3 percent pasture and grasslands and less than 1 percent open water/wetlands.

How does Ohio EPA measure water quality?

Blanchard River Watershed TMDL Report provides detailed information regarding the results of the study, including data from the biological surveys, water and sediment chemistry, habitat conditions and bacteria concentrations in the water.

What is the condition of the Blanchard River watershed?

Ohio EPA surveyed 116 sites to assess the overall water quality in this 771-square-mile watershed. The Blanchard River itself generally showed good quality, however only about 40 percent of the tributary streams met the water quality goals needed to support healthy aquatic communities.

The primary reason for low quality is high algae production caused by excess nutrients running off agricultural fields.

Maintaining natural flow and establishing a connected and shaded riparian corridor is important for protecting water quality and aquatic biological communities. Likewise, stream buffers are appropriate for all land use types in the watershed. Other actions include the following:
