COLLIER COUNTY, Fla.- Our lakes and ponds may be calm now, but the head of Collier County EMS warns - you should think twice before jumping into any freshwater following Monday's furious storms.

"It seems like a good idea because it's hot out, and the water is refreshing but that's not clean water," said Dr. Robert Tober.

Doctor Robert Tober tells WINK News the mix of strong wind and heavy rain stirred up our lakes and ponds so much, there could be sharp glass or even snakes lurking, along with dangers you can't see.

"You have a lot of run-off from the ground, toxins in the ground, pesticides, poisons," said Dr. Tober. "The biggest worry I would have would be for sewage backup. So chloroform bacteria, things that can cause diarrhea, e-coli infections, could even get parasitic infection or ameoba infections from water like that."

Southwest Florida is no stranger to ameoba deaths. Just last summer, 12 year old Zac Reyna died when a rare, brain-eating paraside shot up his nose while he was kneeboarding in freshwater. His father posted on Facebook Tuesday saying "I know the water filled ditches look like a lot of fun for the kids to play in, but please be careful."

Doctor Tober agrees.

"That's always a worry in any of these ponds, cause we don't really know where that ameoba is."
