Nonpoint Source Pollution

The Great Lakes Restoration Initiative is supporting a partnership between St. Louis County, the City of Duluth and U.S. Army Corps of Engineers to implement green infrastructure practices at Hartley Park to protect water quality in Tischer Creek.

A first-of-its-kind study by the University of Illinois found that GLRI Demonstration Farms increased the adoption of cover crops among farmers in Eastern Wisconsin by 50% — a key improvement which will make a lasting impact in reducing nutrient runoff in the region.

The Great Lakes Commission issued a request for proposals for projects that will help improve Great Lakes water quality by reducing nutrient loads from agricultural watersheds and eroding shorelines and streams.

Seven projects in Indiana, Minnesota, New York and Wisconsin were selected for funding through the Great Lakes Sediment and Nutrient Reduction Program.

In Lima, Ohio, researchers at The Ohio State University are testing an innovative water retention system to passively treat runoff before recycling the water back onto the field to irrigate crops.

A GLRI demonstration project is testing the potential for cell lysis technology to protect water quality by lowering the phosphorus content of manure.

The National Oceanic and Atmospheric Administration and various partner institutions are currently testing a forecast model to better predict the timing and location of toxins in harmful algal blooms in the Western Lake Erie Basin.

The Nature Conservancy, Ohio Department of Agriculture, Lenawee County Soil and Water Conservation District, and Regents of the University of Michigan will receive $3,712,124 in grants funded under the Great Lakes Restoration Initiative. By providing technical assistance and outreach to farmers, these organizations will help reduce the amount of nutrient runoff entering Lake Erie resulting in harmful algal blooms.

As a member of the Door-Kewaunee Demonstration Farms Network and Peninsula Pride Farms, Lee Kinnard of Kinnard Farms partnered with the U.S. Department of Agriculture (USDA) Natural Resources Conservation Service (NRCS) and the U.S. Geological Survey (USGS) to be one of the first farmers in the nation to have a denitrifying bioreactor and a phosphorus removal system built in-line on the same tile system within a field.

On Feb. 28, 2025, the Great Lakes Commission (GLC) today issued a request for proposals (RFP) for projects that would help improve Great Lakes water quality by reducing nutrient loads from agricultural watersheds and eroding shorelines and streams.
