One man was able to swim to safety. A man riding by on his bicycle captured video of the rescuers pulling a 28-year-old man to shore.

The 24-year-old woman is still missing.

Fierce waves made it impossible for dive teams to enter the lake to look for her.

“The waves sneak up and pull people in,” Coast Guard Chief Warrant Officer Matthew James said. “I had one come up to my knees and almost pull me down, so if it’s dangerous for me it’s dangers for someone on a bike or out for a jog.”
