The South Florida Water Management District is monitoring what it calls a "significant" algae bloom in Lake Okeechobee. Officials with the Florida Department of Environmental Protection are also keeping an eye on the bloom after it was first discovered last week during a flyover.
Samples were taken from the green algae and test results could be back as soon as today to see if it's toxic.
A mix of warm water temperatures and run-off into the lake from waterways to the north are believed to have caused the bloom. The run-off was brought on by recent rains.
Toxic algae caused big problems last summer, when it wound up in the St. Lucie River due to discharges from Lake Okeechobee.
Right now, the level of the lake is at 12.66 feet and the U.S. Army Corps of Engineers prefers to keep levels between 12.5 and 15.5 feet, so discharges would not likely be necessary.
