The Kansas Department of Health and Environment has removed Marion Reservoir from the ?advisory? list for toxic blue-green algae, as of Thursday afternoon, Aug. 2. When a lake advisory has been lifted, visitors to the lake should still exercise caution and look out for algae blooms in the water, as conditions can change quickly depending on the weather and other factors. Currently, six lakes in Kansas are under an ?advisory? for blue-green algae and six more lakes are under the more severe ?warning.?
