MCPHERSON, Kan. — Visitors to two McPherson parks are being urged to avoid the water after the city issued public health advisories this week for toxic blue-green algae. Following recommendations from the Kansas Department of Health and Environment, the lagoon at Lakeside Park is under a strict warning that prohibits all watercraft and water contact, including for pets.

Meanwhile, the lake at Wall Park was placed on a lower-level watch status, advising residents to avoid swimming or wading near visible cyanobacteria blooms that can produce toxins harmful to both humans and animals.
