TOPEKA– The blue-green algae health advisory at Cedar Bluff Reservoir has been lifted.

The Kansas Department of Health and Environment (KDHE) samples recreational bodies of water for cyanobacteria, commonly called blue-green algae, when the agency is alerted to a potential algae bloom.

As a result of this week’s water sampling, the health advisory was lifted Thursday at Cedar Bluff Reservoir in Trego County.

“When a lake advisory has been lifted, visitors to the lake should still exercise caution and look out for algae blooms in the water, as conditions can change quickly depending on the weather and other factors,” said Farah Ahmed, PhD, KDHE Environmental Health Officer.

Some algae blooms can look like foam, or a thick slurry. The blooms can be blue, bright green, brown or red, and they may look like paint floating on the water. However, some blooms may not affect the appearance of the water.
