The National Oceanic and Atmospheric Administration and its research partners have forecast a moderate harmful algal bloom for western Lake Erie this summer.
The bloom is expected to measure 4.5 on the severity index—making it one of the smaller blooms since 2011—but could possibly range between 4 and 5.5, compared to 7.3 last year. An index above 5 indicates a more severe bloom.
