Swimming in Murray Irrigation channels is not only prohibited, but extremely dangerous, CEO Ron McCalman has cautioned.
"Irrigation channels are designed for water delivery and not for swimming," he said.
"As tempting as they seem on a hot day, there are hidden dangers beneath the water's surface, and a quick dip could cost a life.
"If you want to cool off this summer, stick to safe swimming spots such as local pools."
Submerged objects and weeds, snakes and undertows are among the many hazards that make irrigation channels a treacherous place to swim.
Automated channel infrastructure can open and close at any time without warning, meaning currents and water depths change suddenly.
Moving regulator gates may also crush or trap people who may be swimming at the wrong place at the wrong time.
"We want all members of our community to stay water safe this summer," Mr McCalman said.
"So please steer clear of irrigation channels and choose a safe place to beat the heat."
