Everglades Illustrated: piecing together the Toxic Puzzle

Documentary reveals potential solution to toxic algae exposure Every rainy season in Florida brings the threat of toxic slime in our waterways. At its worst earlier this year, Lake Okeechobee was covered in 400+ square miles of harmful blue-green algae blooms. Thankfully, Floridians have been largely spared in 2023 from large blooms entering the waterways to the east and the west of the lake, but the threat of damaging discharges isn’t over yet. Those of us living near the Caloosahatchee and St. Lucie rivers and their canals, Lake O, and other waters previously tainted with algae know all too well the environmental and economic harm these discharges can bring. Green water clumped like guacamole, with dead fish at the [...]

Everglades Illustrated: Toxic Times Ahead?

The satellite image above from June 11, 2023, presages a grim tale. The algal bloom seen here covers an estimated 440 square miles of Lake Okeechobee which, amazingly, NOAA describes as a decrease from the day before. At just over 14 feet, Lake Okeechobee is higher than anyone is comfortable with at the start of Florida’s rainy season. Comparable levels in past years have led to many billions of gallons of harmful releases to the northern estuaries. Paired with the current concentration of algae in the lake, there’s a concerning likelihood we’re headed toward another toxic summer. Friends of the Everglades spent more than three years fighting for a new lake management plan, LOSOM, that considers the risks of [...]

Everglades Illustrated: Seeing Green (and not the good kind)

Dense blue-green algal mats clump up at the gates of Port Mayaca on May 4, 2023, in Martin County. Photo by Leah Voss It shouldn’t be normal that Floridians fear the threat of toxic algae in the summer months, just as we nervously watch for the approach of hurricanes — but recent, repeated history has given us good reason to be wary. Water managers raised the alarm earlier this year, predicting an intense summer algae bloom on Lake Okeechobee due to heavy rainfall from Hurricane Ian that caused the lake to rise, delivering pollution-loaded runoff from the surrounding areas and killing submerged aquatic vegetation.  Last week we saw signs that this unfortunate prediction may come to pass, [...]

Everglades Illustrated: This is how many sugarcane burning permits are issued in a single day

Last week, Friends of the Everglades Executive Director Eve Samples took to the air with a volunteer LightHawk pilot to survey sugarcane burning in the Everglades Agricultural Area south of Lake Okeechobee. It didn’t take long to find what they were looking for. Within five minutes of takeoff, they spotted several large burns, with smoke and ash blowing westward toward the Glades communities of Belle Glade, South Bay, Pahokee and Clewiston. Elsewhere in South Florida, it was a blue-sky day. But above the Glades, it looked like twilight due to the smoke, known to locals in the Glades as “black snow.” The burns produced so much smoke that the plumes showed up as rain on the LightHawk pilot’s radar. Keep [...]

Everglades Illustrated: Can you guess Florida’s biggest polluter?

Florida’s BMAPs (Basin Management Action Plans) are supposed to provide a framework for cleaning up the state’s most beleaguered waterways. They detail local and state commitments to reduce pollutant loading. Broken down by watersheds around the state, they contain proposed solutions, including permit limits on wastewater facilities, urban and agricultural “best management practices” and conservation programs designed to achieve pollutant reductions established by a Total Maximum Daily Load (TMDL). But a 2022 investigation by TCPalm deduced the program wasn’t working. Why not? The chart above, featured in the latest Deep Dive from our friends at VoteWater, helps to explain it.  Total phosphorus and total nitrogen loading into nine separate sub-watersheds making up the Lake Okeechobee BMAP is broken down [...]

Everglades Illustrated: This is how quickly discharges impact water quality.

Take a look at the photo above. This aerial image, taken by Ed Lippisch of Sewall’s Point, is part of a series he captured while flying over the St. Lucie River and Indian River Lagoon in the early afternoon on February 8 — 17 days after Lake Okeechobee discharges conducted by the Army Corps of Engineers and supported by the South Florida Water Management District started in an effort to lower the lake.  The impact is striking. Dark plumes of polluted Lake O water invade the local waters traversed and lived along by residents of Martin County, drastically impacting water quality. Blue water seen here clearly illuminates the barren moonscapes of Stuart’s shallow-water sandbars, which were once lush with [...]

Everglades Illustrated: Persistent Red Tide

Along the coast of Southwest Florida, red tide is lingering. Through January 6, 2023, the Florida Fish and Wildlife Conservation Commission detected low to high concentrations in 59 samples collected from Pinellas to Charlotte County, as detailed in the image above.  Conditions have varied since October when the blooms first appeared, due to ever-changing wind and currents that move blooms inshore and offshore, as well as up and down the coast. Marine animals and residents alike are feeling the repercussions, as fish kills and respiratory irritation reported by beachgoers are linked to the persistent blooms.  In Sarasota Bay, researchers have discovered that bottlenose dolphins tracked by marine scientists will “cough” and “sneeze” when they swim through strong red tide blooms, [...]

Everglades Illustrated: Sanibel Red Tide Report

Take a look at these photos from Friends of the Everglades Multimedia Producer Leah Voss. The images from a recent visit to Sanibel Island offer a sobering look at a community still very much in distress after Hurricane Ian made direct landfall along Florida’s west coast on September 28. Much of the island remains off limits to visitors as the local population continues the hard work of recovery. The latest threat exacerbating the post-storm situation hangs heavy in the air and the surrounding water — red tide. Along the shoreline, Leah described a nauseating smell and an unmistakable tickle at the back of her throat. A dead seabird laid in the [...]

Everglades Illustrated: Wrong project, wrong place

Last week, Miami-Dade County Commissioners voted 8-4 to approve the South Dade Logistics and Technology District, effectively gutting the Urban Development Boundary in favor of sprawling, industrial development at the expense of our natural environment. The original footprint of the project, identified in the map above, has since been reduced in size from 800 acres to a 311-acre mix of warehouses, call centers and other commercial uses south of Florida’s Turnpike. Regardless, it remains the wrong project in the wrong place, with construction slated for “Coastal High Hazard Area'' in dangerous proximity to Everglades National Park, Biscayne Bay and ongoing Everglades restoration projects. As another tropical storm approaches Florida's coast, it's more clear than ever: It's reckless to bend [...]

Everglades Illustrated: A system overwhelmed

Hurricane Ian barreled into the west coast of Florida on September 28 as a powerful Category 4 hurricane. As relief efforts remain rightly focused on the heartbreaking human toll of the storm, the environmental fallout has yet to come front and center. Satellite images are helping to piece together the beginnings of a story that has only just begun to play out. In the NASA satellite image above, swirls of sediment stirred up in Florida’s coastal water, “lifted from the seafloor as Ian neared the coast,” starkly contrast with dark plumes of stormwater runoff exiting the land. Though this tannin-colored runoff is not altogether unusual, the sheer volume of water coming off the landscape is out of the ordinary, [...]
