Two of only three designated swimming areas at Lake Waco are now closed, because water levels are almost 5 and a half feet lower than usual.
The boeys indicate where the designated swimming areas start and end.
They're there because Park Rangers know these areas are safe.
But out past the boeys are unknown drop-offs and other hazards.
"There's no fine, but we do suggest that everyone that if they do want to swim outside of our designated swimming areas, we would highly recommend that they wear a life jacket and also swim with a buddy, or you know, just do some extra precautionary safety measures," Park Ranger Randall McCartney said.
In order to avoid any dangers and enjoy swimming in the lake again, there's only one sure fix.
"Once we get significant amounts of rain fall, and run off from the rivers, then just the rain itself, that will bring the lake levels back up to normal pool," McCartney said.
In previous years water levels could be up to chest high. But at Airport Beach Park in the designated swimming areas, you can barely get your feet wet.
Back Beach at Twin Bridges and Airport Beach Park are closed to swimmers, but boat ramps are still open.
There is another option for swimmers as well.
"We still have one open. That's the Front Beach at Twin Bridges, that's a day use park, and it still has a little bit of water left in that," McCartney said.
