Scientists predict a significant harmful algae bloom for western Lake Erie this year.

The forecast, a joint effort between the National Oceanic and Atmospheric Administration, Heidelberg University and other partners, predicts a bloom severity of six on a 10-point scale. That would be better than last year, but worse than 2016.

An algae bloom was identified in Lake Erie’s central basin this week, causing increased testing and increased caution at Cleveland’s beaches.

Toxin concentrations were high only one day last week. On Friday, the Northeast Ohio Regional Sewer District detected a concentration of 10 parts per billion at Edgewater Beach. Ohio’s recreational threshold is 6 parts per billion.
