Hot, dry weather causing more blue-green algae at Metropolitan Lake

Alex Her has been fishing panfish and carp at Crystal Lake in Robbinsdale for as long as he can remember.

“This is the lake of my childhood. I always go out and have fun here,” Her said.

He comes to the water to relax, but recently he’s been faced with warning signs of blue-green algae, something stinky and potentially poisonous.

“I saw people swimming and I said, ‘Hey, just stay out of the water!’ Even I, around the bank here, try to avoid it, ”Elle said.

Marta Roser, Robbinsdale’s water resources specialist, says the hot, dry weather this summer is making algae blooms more common on the lake.

“I think the fact that it warmed up very early in the spring contributed to the early algal blooms. We usually don’t see blooms as large as the ones we saw before August,” Roser said.

Blue-green algae looks like a spill of green paint on the water. It can contain toxins that are deadly to pets and toxic to humans if swallowed, and that’s not just a problem in Robbinsdale.

the Minneapolis Park Board Lake Water Quality Map shows that blue-green algae may be present on the beaches of Bde Maka Ska and Lake Hiawatha.

“You can’t tell by looking at the flowers if they have toxins in them, which can make things a little tricky,” Roser said.

If you suspect that the lake water contains blue-green algae, stay outside.

The Minneapolis Park Board of Directors recommended do not swim if you cannot see your feet in the water up to your knees.

If you or your pet accidentally swim in water that may contain blue-green algae, immediately rinse it off with clean water and make sure you don’t let your pet lick their coat.
