The Kansas Department of Health and Environment (KDHE) and the Kansas Department of Wildlife and Parks (KDWP) have announced that the state's harmful algal bloom (HAB) response program is now active for the 2026 water recreation season. Residents are advised to be on the lookout for HABs and harmful algal mats (HAMs) that can produce toxins and cause various health issues through exposure.

Why it matters

Harmful algal blooms can pose serious risks to public health and the environment, especially during the peak water recreation season. This program aims to monitor and respond to HAB incidents to protect Kansans who enjoy activities like swimming, boating, and fishing in the state's lakes and rivers.

The details

The KDHE and KDWP stated that the HAB response program is now operational as of April 1, the start of Kansas' official water recreation season. They warned residents to be vigilant for signs of HABs, which can appear as blue, green, brown, or red discoloration in the water, as well as HAMs that may look like foam, scum, or paint floating on the surface. Both can produce toxins that can cause rashes, vomiting, diarrhea, fevers, sore throat, and headaches through ingestion, inhalation, or skin contact. The agencies will investigate reports of HABs and HAMs and issue hazard, warning, or watch advisories as needed.
