The forecast for Lake Erie this summer looks like there will include another outbreak of algae on the water.
The director of the Ohio Sea Grant College Program says conditions in the lake are looking like they did in 2011 when a massive algae bloom spread from Toledo to Cleveland.
Algae blooms during recent summers have become a threat to the lake's tourism and fishing industries.
Toxins produced by the algae have contributed to oxygen-deprived dead zones where fish can't survive.
Heavy rainfalls this spring means water is washing into the lake and carrying more pollutants that feed the algae.
The official forecast for the algae blooms won't be out until July, but researchers already are bracing for trouble.
