Health officials are warning the public about high levels of toxic blue-green algae in six lakes in Kansas.

The Kansas Department of Health and Environment said in a news release Thursday that direct contact with the water such as wading in it is strongly discouraged for people, pets and livestock.

Those lakes now under a warning status include the Brown County State Fishing Lake in Brown County and Chisholm Creek Park Lake in Sedgwick County. Others are Memorial Park Lake in Barton County and Plainville Township Lake in Rooks County. Also included on the list are the Lovewell Reservoir in Jewell County and the Milford Reservoir in Clay, Dickinson and Geary counties.

Lakes under a warning are not closed.
