Those hazards include debris from winter storms which can be just below the surface.
"Regardless if you're a good swimmer, if you're going into an ocean, lake or river, you should have a personal flotation device on, in each one of these tragedies they did not," said Foreman.
Free loaner life jackets are available for day use at most Sonoma County Regional Park beaches. Gloria Jimenez was grabbing some for her little ones.
