Here are some safety reminders from the Iowa Department of Natural Resources concerning swimming, especially at state parks, beaches, lakes and rivers.
Swim with a buddy, avoid swimming or wading in rivers, always wear a life jacket, and avoid alcohol while swimming.
Stay within the roped-in area of the lake, obey posted signs and flags, and take a water bottle with you to not get dehydrated.
Also remember that Iowa’s public beaches do not have lifeguards on duty, and that glass bottles and pets are prohibited on beaches.
