Stephens Lake closed because of possible harmful algae

Columbia Parks and Recreation has closed Stephens Lake because it might contain harmful algae.

The advisory has been issued by the Missouri Department of Health and Senior Service and was effective Thursday, the city department said in a news release.

Parks and recreation staff and state regulators are working together to test the algae to confirm if toxins are present.

Official will be testing for algal blooms, which are large growths of algae that could reduce the oxygen in the water, producing toxins and bacteria growth that can cause illness.

The news release said there are signs at the park notifying park users of the potential harmful algae.

An algae expert, Lynn Milberg, with the Missouri Department of Natural Resources said exposure could cause cause minor problems like skin and eye irritation, but also much more serious issues as well.

“You’re ingesting large quantities of it, it could affect your liver, some could also produce neuro-toxins, so it could have implications for the brain,” Milberg said

Officials said if people or animals come in contact with the water or algae, they should wash thoroughly as soon as possible.

Parks and Recreation Director, Mike Griggs said it’s the four-legged friends he’s mostly concerned about, who could ingest large amount of water.

“We’re being conservative and cautious, we would rather warns people to stay out, until we have a way to test it,” Griggs said.

Parks and recreation said the lake will remain closed until testing comes back confirming the lake is safe.

City officials said testing will take place tomorrow.

The lake is set to close Sept. 30 for the fall and winter under its normal operating schedule.
