Week 14 of monitoring brought cooler weather, fewer sightings of cyanobacteria, but also far fewer monitors to report them. High alert blooms continued in parts of St. Albans Bay, Lake Carmi, and Lake Morey which have all had persistent blooms during the last weeks or months. Read...

While the weather cooled during Week 13 of monitoring, blooms continued in several lakes or bays where they were present previously and showed up in some new locations.

The samples turned out to be Calothrix sp. – a benthic filamentous cyanobacteria. Read...
