Astrobiology - Algal blooms have become a common occurrence on Lake Erie, as much a part of summer at the lake as island-hopping, scenic cruises, and roller coasters. In 2024, a bloom of blue-green algae began forming in the lake’s western basin on June 24—the earliest that a bloom has been identified by NOAA since the agency began tracking them in 2002. It was still present in early September. Bloom season can last into October, with its duration depending on the frequency of wind events that mix lake waters in the fall.
