It was a big concern when the U.S. Army Corps of Engineers started discharging water from Lake Okeechobee after Hurricane Irma, now potentially toxic blue-green algae is being detected in the Indian River Lagoon.
Scientists say that while it's not enough to be visible, water quality monitors called "kilroys" are detecting the algae. There are a number of those devices placed in the water at sites throughout the Treasure Coast.
Among the locations where the algae was detected were the C-23 canal and the Manatee Pocket in Martin County.
Releases from Lake Okeechobee were blamed on last year's toxic algae crisis, and discharges are continuing, as the lake's level is now above 16 feet, with more time left in Hurricane Season.
