Rip currents can often be seen from the beach as a cloudy stretch of water in between areas of high wave action.
The other current is called a structural current. These currents occur along break walls and the many concrete piers along the shoreline. They form when high waves throw water against the structures. That water has no where to go but further out into the lake.
“They can be pretty fast and some of the measurements that they’ve done recently have been twice faster than Michael Phelps can swim,” Dodson said.
The best way to keep yourself and others safe from these currents is to stay dry when waves are high — and steer clear of the pier. But sometimes we don’t realize how dangerous a situation is until we’re in it.
