With the warm temperatures this weekend, a day at one of Door County's lakes may sound like a good time for the family but it’s important to keep a close eye on children while they’re swimming. Especially swimming in a lake or a pond the water conditions can change rapidly. Ellen Knipfer is a nurse practitioner at Door County Medical Center who has treated many swimming-related injuries. She also used to be a lifeguard and she got used to seeing parents go off and do other things while their children were in the water. 

Knipfer adds people need to be aware Lake Michigan has a strong undertow and that can develop quickly. Other tips include wearing a life jacket when going boating and don’t drink alcohol while going swimming.
