Channel danger

"Irrigation channels are designed for water delivery and not for swimming or playing in.

"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."

Submerged objects and weeds, snakes and undertows are among the many hazards that make irrigation channels treacherous.

Automated infrastructure can open and close at any time without warning, meaning currents and water depths can 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 children, families and 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 escape the heat."
