Today’s Lake Erie Harmful Algal Bloom Bulletin, published by the National Oceanic and Atmospheric Administration (NOAA), reports the presence of a Microcystis cyanobacteria bloom extending from Maumee Bay near Toledo about 13 miles north along the Michigan coast and 15 miles east along the Ohio coast. A persistent bloom in Sandusky Bay, the bulletin reports, is continuing.

Details in the bulletins, which include the locations of blooms and three-day forecasts, can be used to plan your activities at Lake Erie.
A new study of harmful algal blooms in Lake Erie’s central basin, mentioned in an April 23 post, gets deeper coverage in a story today by Ohio State science writer Misti Crane.
Not only do blooms routinely occur in the lake’s central basin, the story says, they can also produce types of cyanobacterial toxins—toxins produced by cyanobacteria, the organisms responsible for harmful algal blooms—that typically aren’t detected through routine water-safety monitoring.
Harmful algal blooms aren’t just a thing in western Lake Erie. They happen in the lake’s central basin too, and when they do, they sometimes produce toxins.
So says a new study led by Justin Chaffin of CFAES’ Stone Laboratory, which set out to learn more about the central basin’s less-studied blooms, including what drives them and whether they produce toxins called cyanobacterial toxins. The toxins, which can threaten human health, must be removed by facilities that treat drinking water.
In areas from rainfall to lake levels, fish to algal blooms, shipping to agriculture, drinking water quality to public health, “Climate change is causing significant and far-reaching impacts on the Great Lakes and the Great Lakes region.”
If you live and farm in Ohio and apply fertilizer to more than 50 acres of land, you need to earn your agricultural fertilizer certification by Sept. 30 of this year. Learn more about the requirement here. See the training dates and locations here. The next training session is May 10 in Cortland in northeast Ohio.
Ohio Sea Grant, on behalf of Ohio State, the University of Toledo and the Ohio Department of Higher Education, has released the annual report for the first year of funding for the Harmful Algal Bloom Research Initiative (HABRI), which seeks solutions for harmful algal blooms in Ohio. Included are details on 18 new studies; some involve CFAES scientists. Read the press release. Read the report.
