Centralia Lake in Nemaha County is included in a warning issued by Kansas health officials. The warning tells people to avoid contact with water in the lake because of toxic blue-green algae blooms. The Kansas Department of Health and Environment says the warnings cover Centralia City Lake in Nemaha County until further notice. KDHE says people should avoid ingesting the water, or swimming or wading in the lake until further notice. Pets should also be kept from contact with the water. KDHE also says people should not eat fish or shellfish from the lake.
The KDHE says blue-green algae are found in most surface waters but in heavy concentrations form blooms, which release toxins. The blooms often resemble green paint floating on the water, and they can produce an unpleasant smell.
