Intense heat has caused algal blooms to form in western Lake Erie much sooner than normal. Though toxin levels are not yet known, officials are issuing their standard advice to stay away from all scums floating on the lake surface…. Read More ›

A budget proposal released by President Donald Trump zeroed out funding for the Great Lakes Restoration Initiative, but members of Congress from the Great Lakes area say they’ll fight to retain it.
The kind of toxic algae that forms each summer on Lake Erie and other lakes around Ohio feeds on phosphorus, a key element of livestock manure and sewage.

Such toxins include heavy metals and chemicals that have long been banned, such as DDT or PCBs, that can have severe environmental effects and are known to cause cancer and birth defects.
