From the sky, you’d be forgiven for thinking parts of the Great Lakes are growing grass. The algae blooms this year are so thick they look like well-fed lawns, albeit ones that could suck you down into the ooze and maybe poison your dog with algal toxins, to boot.
Last month, scientists predicted a “severe” outbreak of algae in Lake Erie,writing:
The effects of the cyanobacterial blooms include a higher cost for cities and local governments to treat their drinking water, as well as risk to swimmers in high concentration areas, and a nuisance to boaters when blooms form. These effects will vary in locations and severity with winds, and will peak in September.More
The bloom will be expected to measure 8.7 on the severity index with a range from 8.1 to potentially as high as 9.5. This is more severe than the last year’s 6.5, and may equal or exceed 2013, which had the second worse bloom in this century. The severity index runs from a high of 10, which corresponds to the 2011 bloom, the worst ever observed, to zero. A severity above 5.0 indicates blooms of particular concern.
Lake Erie in Cleveland has been off limits most of the past 15+ years because just touching your toes in the water can be deadly. This is old news to everyone that has lived or visited there.
