(Portland, OR) -- A lot of people will head to Sauvie Island this weekend to cool off on a Columbia River beach. The Oregon Department of Fish and Wildlife has started a pilot program to reduce traffic and overcrowding at parking lots. A free Sauvie Island Beaches Pass is required along with a Wildlife Area Parking Permit that costs ten dollars a day or 30 dollars a year. You can get the permits online at Sauvie Island Parking dot com. A limited number of passes are available each day and there's a checkpoint to make sure vehicles have the passes.
