Conditions: A confirmed Microcystis bloom persists in Western Lake Erie.You can also view the complete Bulletin in PDF, which shows imagery from the European Space Agency of the bloom's progression. As you can see, it has spread out over much of Lake Erie's western basin.
Analysis: A large Microcystis bloom remains in Western Lake Erie. Model trajectory indicates an easterly transport over the weekend, potentially to Pelee Point by August 21. Recent wind conditions have been relatively low, allowing the biomass to be concentrated in the surface. Low wind stress is predicted over the weekend, so this trend should continue. Water temperatures remain high (nearly 25 C) which should allow the bloom to persist at its present intensities through next week.
This morning I noted that the bloom has encroached into several boat basins on the west side of the Catawba Island Peninsula. The icky green stuff is everywhere.
Swimming is not recommended.
