The City of Olathe was notified today that Cedar Lake (15500 S. Lone Elm Road) has tested positive for high levels of Blue-Green Algae.
Though blue-green algae blooms are natural phenomena, exposure to high levels can be dangerous to both humans and animals. Swimming is not allowed at Cedar Lake, but the City is urging park visitors to be mindful of pets and make sure they do not swim in or drink from the lake until the algae levels are reduced. Users of Cedar Lake are advised to take the following precautions:
Out of extra caution, the City of Olathe posted signs at the lake alerting visitors. The City is working closely with the Kansas Department of Health and Environment to assess and monitor the situation. Once it is determined that lake algae levels are safe, the signs will be removed and the public notified.
