REND LAKE, IL (KFVS) - The beaches at Rend Lake in Franklin County are packed for the Memorial Day weekend.
And the park rangers with the U.S. Army Corps of Engineers are out in force to ensure everyone is safe, while having fun.
"We have extra staff on, we have rangers patrolling the beaches, out on the water and in the campgrounds," said Mark Roderick with the U.S. Army Corps of Engineers. "We have a lot of people out here, a lot of them are out for the first time. They're probably not used to being out in this heat."
This past summer two people drowned while swimming at South Sandusky Beach on Rend Lake.
"Heat like we're having right now with the temperature and humidity it's bad for everybody," said Roderick. "Recognize your swimming ability. Especially if you're hot and tired don't go out in water that you can't stand in. If you go under somebody may be close enough, but there may not be anybody close enough to help you. It doesn't take that long to drown."
Which is why many parents at the beach keep a close eye on their kids when they're in the water.
"We keep a close watch on everything that's going on out here," said John Markus of Mt. Vernon. "We make sure that they don't go out into deep water. And we go out swimming with them."
The combination of the heat and cool water can be dangerous to some swimmers.
"Don't over exert yourself when you're in the water. Especially if you're hot or tired and you get in the water. The water may be cooler, it can have an effect on the body. It may cause your muscles to cramp up or go into seizures. And that can limit your swimming ability."
The added patrols on the beaches and out on the water at Rend Lake will continue throughout the holiday weekend.
