South Carolina’s state parks are adopting a flag system for its waterways to alert swimmers about water conditions.
State Parks Director Phil Gaines told the Beaufort Gazette that the flags will start flying once the weather warms up in April.
Employees will fly a green flag when there are few problems, with yellow and red flags showing medium and high danger. Two red flags will fly when it is unsafe to swim at all and a purple flag will fly when dangerous marine life is around. Park rangers will be responsible for posting flags each morning and as conditions change, Gaines told the paper.
Similar flag systems are already being used at many town-operated or private beaches in South Carolina.
Officials say exact requirements for the flags are still being written.
South Carolina operates swimming areas at four state parks. Myrtle Beach State Park and Huntington Beach State Park have lifeguards along their beaches, while Edisto Beach and Hunting Island do not.
