Oct 14, 2013 — Big, ugly algal blooms are reappearing in the western basin (and sometimes the central basin) of Lake Erie. The blooms happen when excess nutrients - mostly phosphorus - run off into the lake from farms and sewage treatment plants. Some of these kinds of algae produce toxins that are among the most powerful natural poisons on Earth.
Over the past decade, these algal blooms have been common in Lake Erie. And scientists predict climate change could make the problem worse.
