Science alone won’t save the lake: Agricultural runoff in the Western Lake Erie Basin.

Facing facts and moving forward: Notes from the 2025 State of the Western Lake Erie Basin Conference.

On June 26, the State of the Western Lake Erie Basin (WLEB) conference, hosted by Michigan’s Department of Environment, Great Lakes, and Energy (EGLE), brought together researchers, agency staff, and community advocates working in one of Michigan’s most heavily farmed—and heavily polluted—regions.

The focus was on advancements and priorities in the WLEB, especially efforts to tackle harmful algal blooms (HABs). Highlighted tracks included:

  • Implementation Science in Agricultural Systems: Potentials for and Assessments of Innovative Behavior Change Interventions
  • Healthy Soils, Healthy Waters: Understanding Links Between Soil Health and Water Quality on Farms in the Western Lake Erie Basin
  • and Understanding Legacy Phosphorus in the Western Lake Erie Basin.

A common theme ran through all sessions: the problem is well understood—now is the time to implement real solutions to reduce pollution.

Agricultural runoff is the main issue.

EGLE made it clear that the biggest threat to the WLEB is non-point source pollution, particularly runoff from agricultural sources. That aligns with what they’ve stated in their MI Environment article about harmful algal blooms (HABs). The article explains, “In May, the State of Michigan updated its Domestic Action Plan (DAP) for combating harmful algal blooms (HABs). The plan contains measures to reduce phosphorus runoff by a sustained 40% from a 2008 baseline measurement by targeting nutrient-rich releases from wastewater treatment plants and phosphorus runoff from farm fields and fertilized lawns.”

Presenters reiterated throughout the day that this problem isn’t new and it’s not only about current practices. Decades of fertilizer use have left legacy phosphorus in soils and sediments. Addressing these long-term consequences is critical to building effective, lasting solutions and achieving sustainable land management.

People are trying new things.

Despite the challenges, there were some encouraging updates. One session focused on using behavioral science—not just facts and figures—to help understand how farmers make decisions. Findings show that simply providing more information doesn’t always lead to action; real change requires meeting people where they are.

Another panel showed how improving soil health can also help reduce runoff. However, even with these promising tools, a major theme emerged again: none of it will scale up without stronger policies to support it.

Policy support is the missing piece.

A major challenge is the damage resulting from environmental rollbacks. During the Trump administration in 2020, agencies like the EPA and USDA weakened review processes, referring to it as “permitting reform.” In truth, these changes limited public input and undermined environmental protections. Fact sheets from that time detailed reduced deadlines and page counts—presented as cutting red tape—but in practice, these reforms made it easier for large-scale projects, including agricultural operations, to bypass environmental scrutiny. That’s a serious concern in regions like Western Lake Erie.

Science alone won’t save the lake.

The conference underscored a key takeaway: science alone isn’t enough to solve nutrient pollution. Policies rooted in strong science—and the enforcement to support them—are essential. Otherwise, even the best ideas remain stuck in pilot programs.
The case of the Western Lake Erie Basin shows what happens when known problems go unaddressed—but also what’s possible when land use and water protection are treated as urgent, interdependent priorities.

At Flow Water Advocates, the work continues to advocate for policies that protect Michigan’s water and communities. Clean water depends on effective protections—and real accountability—when it comes to farming, development, and pollution.

Nutrient Pollution: The Second Battle of Lake Erie

Published on October 9th, 2024 by - Blog Posts

One of the military clashes between England and the United States was the battle of Lake Erie. On September 10, 1813, nine ships under U.S. Master Commandant Oliver Hazard Perry bested a nine-ship English fleet in a decisive battle for control of western Lake Erie and surrounding lands. Today, a 352-foot International Peace Memorial on South Bass Island commemorates the longest undefended border in the world, uniting Canada and the U.S. 

For more than three decades now, our nations have engaged in a different kind of struggle – to rescue western Lake Erie from a tsunami of toxic algae. No one is winning except the industrial agriculture interests that profit from lax environmental regulation, as untreated factory farm sewage is allowed to pour into Michigan’s formerly pure waters. We need a fundamentally different approach to nutrient pollution.

When detergents in wastewater caused algae blooms in the 1960s, the U.S. and Canada moved quickly to control the culprit – phosphorus – with dramatic improvements in just a few years. The battle was won, but the war wasn’t over. Beginning in the 1990s, annual algae blooms returned to western Lake Erie, growing in severity until, in 2014, Toledo, Ohio had to shut down its drinking water intake and put the entire city on bottled water for days. Tens of millions of taxpayer dollars spent on cleanup strategies in the past decade have done little to diminish the threat to Lake Erie and its many tributaries, which used to be swimmable and fishable. Today, they run brown and weedy, choked with ag-sourced sewage.

Nutrient pollution includes nitrogen and phosphorus, both products of agriculture and other human activities. It’s tricky to regulate because nutrients are essential to the food cycle, but too much quickly turns toxic for humans and animals alike. Nutrient pollution causes fish kills and dead zones. It contaminates private wells by leaching through soil. Exposure can cause diarrhea, nausea, vomiting, irritation of the skin, eyes, and throat, allergic reactions, or breathing difficulties. Prolonged exposure can cause cancer.

Wastewater plants were responsible for some of the nutrient pollution, but research quickly identified factory farms as the leading source of the algae resurgence.

The International Joint Commission, which deals with issues affecting waterways along the U.S.-Canada border, called for a 40% reduction in phosphorus in western Lake Erie, but every year we miss that goal by miles, despite an agreement by Ohio, Michigan, and Ontario to reach the 40% goal by 2025. They won’t come close. Western Lake Erie’s target phosphorus load was met only once from 2013 through 2024. Some say there has been virtually no reduction. This year’s bloom was detected on June 24, the earliest date ever, reaching 620 square miles, and was still visible as October began.

Clearly, we need more tools in our toolbox. In other parts of the world, holistic approaches to nutrient pollution show promise. The Netherlands, for example, has implemented “nitrogen accounting,” which makes individual sources of nutrient pollution responsible for tracking their outputs. It’s a flexible approach that allows for creativity and customized practices at the local level, as long as nutrient outputs stay below the required levels.

Nutrient pollution has become a global problem that requires innovative, game-changing thinking and cross-border collaborations. We have no time to lose.
