Why should I be aware of blue-green algae?
Some blue-green algae produce toxins that pose a health risk to people and animals. Health effects could occur when surface scums or water containing high levels of blue-green algal toxins are swallowed, through contact with the skin or when airborne droplets containing toxins are inhaled while swimming, boating, and skiing. A large percentage of the public will report "allergic" type reactions after exposure to blue-green algae, such as intestinal problems, respiratory problems, or skin irritations. Harmful Algae Blooms can appear (or disappear) rapidly. Always be mindful of any unusual look to the lake including a green or brown color, scum, paint-like appearance, or odor.
Kansas has had numerous dog deaths and human
illnesses reported in the past.
What should I do if I see a bloom?
When in Doubt Stay Out. If you see what might be a bloom, please let the lake manager or other lake official know of your concerns and complete the Algal Bloom Report Form. A “Jar Test” will be requested and if the complaint is validated, sampling will begin within that week.
