Medford, Ore. – High temperatures have arrived in southern Oregon, and experts are warning the public to be careful in local waterways that are still cold due to snow runoff.
Experts say suddenly falling or diving into water 70° or less can trigger an involuntary gasping response. If you’re underwater, you will breathe in water.
The National Center for Cold Water Safety said if you do survive the gasp response, hyperventilation follows–making it nearly impossible to swim even a short distance. They added if you’re not wearing a personal floatation device, “you will drown.”
As of May 22, the water temperature of the Rogue River at Grants Pass is hovering between 59° and 56°, according to the U.S. Geological Survey.
The North Umpqua River near Toketee Falls is even colder, varying between 51° and 48°.
Those temperatures are within the threshold to trigger cold water shock, and hot weather only contributes more to the shock.
According to the Army Corps of Engineers, the unusual conditions in Oregon rivers have already claimed five lives this season.
With Memorial Day right around the corner, experts say to be prepared and cautious when recreating in or around local waterways.
The Corps said wearing a life jacket keeps you afloat until you regain control of your breathing.
