A Great Lakes cleanup program that may be on the Trump administration’s chopping block has plunked money into fighting Lake Erie’s toxic algae and putting new life into Ohio’s polluted rivers.

The Great Lakes Restoration Initiative also has spent millions on cleaning up beaches and restoring wetlands that filter pollutants along the lake shore. In all, Ohio has received just over $200 million in federal funding from the program since 2011.

But that funding could dry up soon, according to a draft of the Environmental Protection Agency budget proposal obtained by The Associated Press.
