It has been predicted that the western Lake Erie will have a significant bloom of cyanobacteria, a toxic blue-green algae, during the 2014 bloom season in late summer. However, the predicted bloom is expected to be smaller than last year's intense bloom, and considerably less than the record-setting 2011 bloom.
Bloom impacts will vary across the lake's western basin and are classified by an estimate of both its concentration and how far it spreads.
Harmful algal blooms (HABs) were common in western Lake Erie between the 1960s and 1980s. After a lapse of nearly 20 years, blooms have been steadily increasing over the past decade. Since 2008, NOAA has issued weekly HAB bulletins for western Lake Erie through the National Centers for Coastal Ocean Science (NCCOS) to give warnings of bloom development. Also, this marks the third time NOAA has issued an annual outlook for western Lake Erie.
"The Lake Erie harmful algal bloom forecast, combined with NOAA's weekly HAB Bulletins, underscores the importance of having accessible and reliable environmental intelligence so the public and environmental health specialists can make informed decisions," said Holly Bamford, assistant NOAA administrator for the National Ocean Service. "With this information, we can work collectively to understand harmful algal blooms and mitigate risk to humans and marine ecosystems."
