Algae is blooming on Lake Okeechobee, creating concerns of a more wide-scale bloom that choked nearby waterways with thick green goo in 2016.
Audubon Florida Lake Okeechobee expert, Dr. Paul Gray, says the lake has way too much nutrient pollution.
"It comes from the farms and cities around the lake and mostly that means phosphorus and nitrogen and those are basically fertilizers," said Dr. Gray.
He says he found the glowing green algae at the Pahokee Marina with people fishing in it.
"There's no signs up saying warning if there's algae you should be cautious about handling the fish. I just think our agencies should be responding much more strongly, to tell people about what's going on," said Dr. Gray.
Dr. Gray believes the algae is a threat to public health and wildlife.
The algae blooms from last year's discharge, caused beaches to close, killed marine life and hurt the local economy.
The Florida Department of Environmental Protection reportedly said tests of Lake O algae have so far been negative for toxins.
