 Oregon's Marine Board is warning stand-up paddleboarders to use the right safety equipment after a Portland woman drowned last weekend in Corvallis. Paddleboards typically come with a standard ankle leash, but users are urged to get a quick-release leash if they plan to float a river. Leashes can snag on rocks or logs in the water, and the river's flow can pull the paddleboarder underwater. The standard, non-quick-release leash should only be used on flat water like a lake.
