Swimming season is returning, and most beaches at Missouri state parks will be open for the Memorial Day weekend.

The Department of Natural Resources reports two beaches will remain closed for the opening weekend. The day-use beach at Harry S. Truman State Park will be closed after a test showed high bacteria. In southeastern Missouri, the beach at Lake Wappapello State Park will be closed because of flooding.

State park officials test the water at swimming beaches weekly during the swimming season.
