Nutrient runoff, especially phosphorus, in Michigan’s Western Lake Erie Basin (WLEB) is a growing problem. It causes harmful algal blooms in Lake Erie, affecting water quality and drinking water safety. Since the 2014 Toledo water crisis, efforts have been made to reduce phosphorus levels, but more work is needed to meet long-term goals.
In 2018, Michigan, Ohio, and Ontario set a target to cut phosphorus entering Lake Erie by 40% from 2008 levels by 2025. While Michigan met the 20% goal in 2020—mainly by reducing point source pollution from wastewater plants—the state is not yet on track to meet the 40% goal. Most remaining phosphorus reductions must come from nonpoint sources like farm runoff in the River Raisin and Upper Maumee watersheds.
Recent data show that phosphorus from farm fields still contributes to large algal blooms. New research reveals that nitrogen also increases bloom toxicity. Fields with high phosphorus levels from past overuse are among the biggest sources of phosphorus loss.
To improve water quality, the state has focused on five priority watersheds. Conservation practices like wetland creation and controlled drainage are being used to lower nutrient runoff. Programs like the Michigan Agriculture Environmental Assurance Program and EGLE’s Soil Health Incentive Program provide support to farmers for using cover crops and precision equipment.
Michigan released its updated 2025 Domestic Action Plan, outlining new strategies to meet the 40% reduction goal. A Community Advisory Group, made up of local leaders and experts, helps guide these efforts. Public meetings, bus tours, and webinars also help educate communities about water protection.
Water quality progress is tracked through new monitoring stations in key areas. The final action plan will be available online through MDARD and EGLE. With continued teamwork, Michigan hopes to restore Lake Erie’s health and meet its water quality goals.
