WICHITA, Kan. (AP) — Health officials are warning people of toxic levels of blue-green algae in several lakes. The Kansas Department of Health and Environment has issued health warnings for Cheney Lake in south-central Kansas, the Sebelius Reservoir in northwest Kansas and the Marion Reservoir in central Kansas. The health warning for the Marion Reservoir does not include Marion County Lake. Officials say people, pets and livestock should not drink the water and should avoid swimming, wading or skiing. A less-serious advisory also was issued for McLaughlin Lake in south-central Kansas.
