  • Staff Report 

In the concluding week of the 2023 HABs bloom monitoring, two confirmed and three suspicious blooms were identified.


Throughout the year, 51 confirmed and 19 suspicious blooms were reported. Breaking down by months, July saw seven blooms, August recorded six, September had ten, and October peaked with 28.

A total of 695 shoreline reports were submitted by volunteers during the season. While October typically sees the most blooms, the emergence of blooms in late July was unprecedented in the monitoring history.

The SLPWA extends heartfelt gratitude to its volunteers, emphasizing the project’s significance for the community and the organization.

Though the official monitoring has concluded, locals are encouraged to report any blooms they spot to [email protected], including pictures and the bloom’s location. Volunteers will maintain their vigilance over the lake.
