A popular Columbia lake is closed while state officials test the water quality. 

Potentially dangerous levels of blue-green algae are growing in Stephens Lake.

Signs are posted warning residents to stay out of the water as a precaution. The algae has not been tested yet in the lake.

Humans could experience skin and eye irritation, the Department of Health and Senior Services said.

“It is one of the few algae that are toxic to both animals and humans- and more so to animals like dogs,” Columbia Parks and Recreation director Mike Griggs said. 

If a dog still gets into the lake, Griggs recommends washing it right away.

“What they really need to be concerned about is whether their pets get in the lake and ingest anything,” Missouri Department of Agriculture spokesperson Sammi Jo Freeman said. “If any of the water is ingested at this point in time, just monitor them very closely and make sure to be working with the veterinarian that your pet sees on a regular basis.”

The Missouri Department of Natural Resources tested the water Friday.

It will take a few days to treat the lake if the department finds toxic levels.

The lake is scheduled to close for the season Sunday, Sep. 30.
