Join the Movement to Clean Up Lake Erie

Every summer, communities and businesses around Lake Erie worry about toxic algal blooms. They wonder if the algae will:

  • Make their drinking water unsafe, like it did in 2014,
  • Put the 117,000 jobs connected to Lake Erie at risk, and
  • Stop Ohioans and visitors from enjoying boating, swimming, and visiting Lake Erie shorelines.


Lake Erie’s algal blooms are caused by runoff pollution. This type of pollution occurs when rainfall washes fertilizer and manure spread on farm fields into streams that flow into Lake Erie. This creates algae blooms each year that can make water toxic to people, pets, fish, and wildlife.


This problem is preventable. Scientists studying Lake Erie report that reducing the amount of runoff pollution will significantly reduce algal blooms and improve the lake’s health.


Less than two years ago officials from Ohio, Michigan and Ontario pledged to reduce the pollution flowing into Lake Erie by 40%. It was a historic moment and a goal that would significantly improve the lake’s health. But meeting that goal will not be easy. You can help.


Tell us you support a healthy Lake Erie agenda:

I'm ready. 

I'm ready to join the tens of thousands of people who care about the health of Lake Erie, the source of drinking water for nearly 11 million people. I pledge to support a healthy Lake Erie agenda that includes:

- Supporting mandatory rules to limit runoff pollution from agriculture
- Listing Lake Erie as impaired under the Clean Water Act, which provides more resources to reduce pollution
- Holding officials accountable to their pledge to reduce pollution by 40%, the level that would significantly improve Lake Erie's health

I pledge to stand up for Lake Erie.
