NOAA and its research partners are forecasting that western Lake Erie will experience a smaller-than-average harmful algal bloom (HAB) this summer, which would make it less severe than 2021 and more akin to what was seen in the lake in 2020.
NOAA and its research partners are forecasting that western Lake Erie will experience a smaller-than-average harmful algal bloom (HAB) this summer, which would make it less severe than 2021 and more akin to what was seen in the lake in 2020.
This year’s bloom is expected to measure 3.5, with a potential range of 2-4 on the severity index — whereas last year’s bloom was measured at a 6.
The index is based on the bloom’s biomass — the amount of algae — during the peak 30 days of the bloom. An index above 5 indicates more severe blooms. Blooms over 7 are particularly severe, with extensive scum formation and coverage affecting the lake. The largest blooms occurred in 2011, with a severity index of 10, and 2015, with a severity index of 10.5.
“Toxic algae affect not only the health of people and marine ecosystems, but also the health and vibrancy of local and regional economies,” said Nicole LeBoeuf, Assistant Administrator for NOAA’s National Ocean Service. “Like with the weather, environmental forecasts are an important tool that can empower communities to more effectively prepare for these events and are a huge part of NOAA’s service to the nation.”
