Public health warnings have been issued for seven Kansas lakes because of dangerous levels of toxic blue-green algae. Less restrictive advisories have also been issued for two additional lakes.

The warnings from the Kansas Department of Health and Environment prohibit swimming, wading, skiing or other direct contact with the water.

Also listed are Memorial Park Lake in Barton County, Riggs Park Lake in Sedgwick County and Rose’s Lake in Johnson County.

The agencies posted advisories for Atchison County Park Lake in Atchison County, and South Park Lake in Johnson County. The advisories allow boating and fishing but strongly discourage direct water contact.
