(KNZA)--A public health warning has been issued for the Hiawatha City Lake due to the presence of high levels of toxic blue-green algae.

The Kansas Department of Health and Environment announced Thursday the lake is among six in the state placed under " warning" status.

KDHE says activities such as boating and fishing may be safe but direct contact with the water should be avoided. 

Fish may be eaten if they are rinsed with clean water. However, you should consume only the fillet portion and discard all other parts.

KDHE will continue to monitor the lake.
