As many families return to the water this summer, officials warn swimmers to be prepared.

Captain Mark Noorman of Grand Rapids Fire Department said it’s important to remember that even inland lakes and rivers contain real dangers like strong currents, submerged debris and drop-offs.

“It's a place to have fun,” he said. “But it can turn dangerous real quick.”

During the weekend, a 15-year-old boy was taken to the hospital after a swimming accident in an Ottawa County lake. Per the sheriff’s office, the boy was underwater for about 10 minutes before he was rescued.

In this case, there were no buoys marking off a safe swim area.

“The buoys will be a reminder just to keep you in closer to the shore where it's a little shallow or a little safer,” Noorman said. “Some lakes don’t have them and you've got to be careful anytime you go near a body of water.”
