Blue-Green Algae Update
We have been receiving a lot of inquiries from concerned lakefront owners due to the blue-green algae blooms that appeared on our lake this year. Blue-green algae is in all area lakes to some extent, and Bear Lake has been one of the few lakes in the state with no large outbreaks over the last several years.
As soon as some suspicious algae was visible on the lake, we reached out to PLM who is our lake management and treatment provider. They came out the next business day and treated 10 acres of shoreline where the bloom was most concentrated, and took a sample which confirmed it was blue-green algae.
With a 455-acre lake, treating a planktonic algae bloom is challenging because the algae is constantly moving with the wind and water movement while also being suspended within the water column. EGLE regulations also limit how aggressively we can treat these blooms, and PLM can only treat developed shorelines, out to 5 feet of water or 100 feet out (whichever is shorter), so we are unable to apply algaecide across the entire lake (not to mention how costly that would be)
PLM will be back on the lake tomorrow (Tue June 30) to do their regular monthly treatment for invasive species, and if there are additional shoreline areas with significant accumulations, they will treat those locations.
The BLLB does want to set realistic expectations. With the heat wave forecasted for this week, new algae growth will most likely continue to develop, even after Tuesday’s treatment. Unfortunately, that’s one of the biggest challenges with managing planktonic blooms. They are driven largely by weather conditions and nutrient availability. PLM feels our remarkable wet spring resulted in an increase in nutrient runoff into the lake, and that coupled with our heat wave will create ideal conditions for blue-green algae to continue to grow.
The BLLB is concerned about keeping Bear Lake as healthy as possible, and we will continue to do that to the best of our ability.
