The Minnesota Pollution Control Agency (MPCA) found toxins in Beaver Lake near Ellendale, Minnesota.
The MPCA reported Thursday that these toxins point to harmful algal blooms, which pose health risks to people and animals.
What’s strange is that Beaver Lake was just checked off as being good for swimming and fishing.
The MPCA, Cannon River Watershed Partnership, and others finished a study that looked at Beaver Lake, among other areas. Beaver Lake met water quality standards, the MPCA reported.
This find comes after the MPCA looked at water samples from large algal bloom. a reported sewage spill. That bloom was reported earlier as a sewage spill.
People who visit the lake often should be aware of how these algal blooms affect them.
“The toxin detected in the recent Beaver Lake water samples must be swallowed to be harmful,” the MPCA said in a press release.
Animals, including dogs, died from drinking lake water with these toxins in extreme cases.
“If noticing a severe algal bloom in the water or scum on shore, people should avoid contact with the water and prevent their pets from swimming in or drinking the water,” the organization said.
Identifying blooms can be difficult. It’s often that it looks like pea soup, but not always. It’s important to avoid contact with the blooms.

“There are currently no short-term solutions to fix a blue-green algal bloom. Once a bloom occurs, the only option is to wait for the weather to change — significant rainfall, wind shifts, or cooler temperatures — to disrupt the algae’s growth,” the MPCA reported.
To prevent future blooms, water quality needs to increase. For this to happen, runoff that’s carried to lakes needs to stop.
What can help Beaver Lake:
Buffers, manure and fertilizer management on crops and lawns, controlled cropland drainage, planting cover crops and sewer system upgrades and maintenance.
