(KNZA)--A public health warning for the Hiawatha City Lake has been lifted. 

The Kansas Department of Health and Environment last week had placed the lake on warning status due to the presence of high levels of toxic blue-green algae.

A news release from the agency Thursday indicated the lake is no longer under warning status.

KDHE says lakes under warning aren’t closed, but that contact with the water can cause serious illness and should be avoided.

Two lakes in south-central Kansas, Cheney Lake and Marion Reservoir, are currently under a warning status due to the presence of high levels of  toxic blue-green algae.
