More people across Oregon headed to the rivers and lakes in recent days, as the region experienced a stretch of warm, sunny weather.
But officials say residents should use caution before plunging into the water. Cold temperatures, unpredictable currents and poor preparation all present potential dangers.

Jason Tyrus, a deputy with the Multnomah County River Patrol, said anyone operating a boat should have a fire extinguisher and enough life jackets for everyone aboard. He also recommended researching the body of water before visiting.
“I see sometimes people underestimating the power of the rivers,” Tyrus said. “It’s not a swimming pool. The river is ever-changing.”
But one of the greatest dangers this time of year is cold water shock. When swimmers suddenly immerse themselves in freezing water, it can cause them to involuntarily inhale and suck in water. Tyrus said the waters are still around 45 degrees Fahrenheit, and hypothermia is possible if people are in the water for too long.
The potential dangers of the water have already been on display this year. Last week, a 20-year-old California man went missing while kayaking near Willamette Falls. It’s possible the man didn’t know the location of the falls before entering the water, according to the Clackamas County Sheriff’s Office.
Metro distributes life jackets at all of its parks. Spokesperson Hanna Erickson said properly worn life jackets can help if a swimmer falls off a boat, or encounters hazards in the water. Rivers can have sudden dips and branches that snag limbs.
“It’s really important to us that we emphasize the message that life jackets are for everyone, and so that’s why we have life jacket stations at all of our parks,” Erickson said.
