PORTLAND - Rushing, high rivers are creating trouble for river traffic and commuters.

On Friday, The river patrol pulled a small boat back from shore which had come loose because of the high waters on the Willamette.

There is also still a lot of debris runoff to watch out for.

Patrol crews said if you're headed out this weekend-keep in mind: most of the small islands or beaches you normally dock on, just don't exist.

You don t know what s on the surface and you run over it, it could damage a prop and that s where you lose your power, your ability to move forward or backwards, pointed out Sgt. Travis Gullberg with the Multnomah County Patrol.

Currents are moving dangerously fast and the water is around 47 degrees. Rescuers say in water like that it would only take 10 minutes to get hypothermia.

Oregon Department Of Transportation officials said the rising river waters have also been forcing bridge operators to lift spans a lot more often.

On average, There are two to three bridge lifts a month -- Thursday morning alone there were five lifts before noon.

A flood watch remained in effect for the Columbia through Saturday.

This is not a situation that is going away any time in the next few days, ODOT's Don Hamilton said. We are looking at seeing increased water flow. It may be a warm weekend so we could see increased snow melt in the mountains and that's gonna have a corrosponding effect on all the rivers in the area.

The Columbia River is already nearing 18 feet, and is more than a foot above flood stage.

Boaters and swimmers are not requires to wear a life vest over the age of 12, but whether you re on a boat or something smaller like a kayak, you have to have a life vest with you. If you don't, tickets could cost $250.
