FWC now accepting applications for newly created Vessel Turn-In Program

FWC logo

The Florida Fish and Wildlife Conservation Commission (FWC) is now accepting applications for a recently approved and newly created Vessel Turn-In Program, a key component of Florida’s derelict vessel prevention program.

VTIP is a voluntary program designed to help owners dispose of their unwanted at-risk vessels before they become derelict. Upon approval of an application, VTIP will take a surrendered vessel and dispose of it at no cost to the boat owner. Removing the vessel before it deteriorates into a derelict condition will prevent legal ramifications for the vessel owner and will protect Florida’s valuable seagrass resources, marine life, and human life, safety, and property.

A derelict vessel upon waters of the state is a criminal offense and can carry serious penalties and fines or possible jail time.

“Acting now is the best way to prevent legal action from occurring if the vessel becomes derelict,” said Phil Horning, VTIP Administrator.

To qualify for VTIP, a vessel must be floating upon waters of the state of Florida and cannot be determined derelict by law enforcement. The owner must have at least one written at-risk warning or citation and possess a clear title to the vessel.

To apply for or view program guidelines, visit or call the FWC Boating and Waterways Division at 850-488-5600 for more information.

Expedition retraces a legendary explorer’s travels through the once-pristine Everglades

Changes in water quality will be an important facet of the expedition

In 1897, the explorer and amateur scientist Hugh de Laussat Willoughby climbed into a canoe and embarked on a coast-to-coast expedition of the Florida Everglades, a wilderness then nearly as vast as the peninsula itself and as unknown, he wrote, as the “heart of Africa.”

Willoughby and his guide were the first non-Native Americans to traverse the Everglades from the Gulf of Mexico to the Atlantic Ocean, and Willoughby’s meticulous notes, charts and water samples would form the basis of scientists’ historical understanding of the legendary “river of grass.”

Now a new expedition has retraced his trek, with the goal of measuring the impact of modern humanity on a watershed that today is among the most altered on Earth and responsible for the drinking water of some 12 million Floridians.

The expedition also commemorates the 75th anniversary of Everglades National Park, which was dedicated on Dec. 6, 1947.

“We think we will see the full spectrum, from one of the most remote parts of the continental United States to one of the most urbanized parts of the United States – all in one watershed, all in one trip,” said Harvey Oyer, co-leader of the four-member expedition and the author of a series of children’s books about the historical Florida frontier. “That, I think more than anything else, will illustrate humanity’s impact from the time of Willoughby to today.”

Willoughby’s thorough work provides a tantalizing opportunity to compare conditions in the Everglades then and now. Traveling the region’s rivers and canals over six days and some 130 miles, Oyer and the team drew water samples from the same spots as Willoughby, according to coordinates he documented, sometimes from some of the most remote and hard-to-reach parts of the subtropical region.

The water samples are being analyzed at the University of Florida for the same constituents that Willoughby examined, such as magnesium and sulfates, along with nutrients now known to affect the Everglades like phosphorus and nitrogen.

The samples are also being tested for modern pollutants like microplastics, perfluoroalkyl and polyfluoroalkyl substances (PFAS), pesticides and pharmaceuticals. It will be a few months before the analysis is complete. The team wrapped u

How floating wetlands are helping to clean up urban waters

As cities around the world look to rid their waterways of remaining pollution, researchers are installing artificial islands brimming with grasses and sedges. The islands’ surfaces attract wildlife, while the underwater plant roots absorb contaminants and support aquatic life.

Floating wetlands were first tested in retention ponds, the kind often located near developments to hold stormwater, to see if they filtered pollution. “The front end of it was, ‘Will they work? How well do they work? And what plants should we recommend?’” says Sarah White, an environmental toxicologist and horticulturalist at Clemson University who has worked on floating wetlands since 2006. Partnering with researchers at Virginia Tech, White found that the wetland plants she tested not only did well in ponds with lots of nutrient pollution, but the adaptable, resilient plants actually thrived. She did not always choose native plants, opting instead for those that would make the islands more attractive, so that more urban planners would use them.

Seminole County Dept. of Health issues Health Alert for Lake Howell and Deep Lake

SANFORD – The Florida Department of Health in Seminole County has issued a Health Alert for the presence of harmful blue-green algal toxins in Lake Howell (Casselberry) and Deep Lake (Oviedo). This is in response to a water sample taken on November 14th and 15th respectively. The Lake Howell alert expires on December 14, 2022, and the Deep Lake alert expires on December 15, 2022. The public should exercise caution in and around Lake Howell and Deep Lake where algal blooms are present. Residents and visitors are advised to take the following precautions:

  • Do not drink, swim, wade, use personal watercraft, water ski or boat in waters where there is a visible bloom.
  • Wash your skin and clothing with soap and water if you have contact with algae or discolored or smelly water.
  • Keep pets away from the area. Waters where there are algae blooms are not safe for animals. Pets and livestock should have a different source of water when algae blooms are present.
  • Do not cook or clean dishes with water contaminated by algae blooms. Boiling the water will not eliminate the toxins.
  • Eating fillets from healthy fish caught in freshwater lakes experiencing blooms is safe. Rinse fish fillets with tap or bottled water, throw out the guts and cook fish well.
  • Do not eat shellfish in waters with algae blooms.

What is blue-green algae?

Blue-green algae are a type of bacteria that is common in Florida’s freshwater environments. A bloom occurs when rapid growth of algae leads to an accumulation of individual cells that discolor water and often produce floating mats that emit unpleasant odors.

Some environmental factors that contribute to blue-green algae blooms are sunny days, warm water temperatures, still water conditions and excess nutrients. Blooms can appear year-round but are more frequent in summer and fall. Many types of blue-green algae can produce toxins.

Is it harmful?

Blue-green algae blooms can impact human health and ecosystems, including fish and other aquatic animals.

Record water levels on St. Johns River pose major flooding risk in Florida (again)

As residents around the St. Johns River continued to pick up the pieces in the aftermath of Ian, Hurricane Nicole impacted the area and worsened already difficult recovery efforts.

After weeks of dealing with the fallout from Hurricane Ian, Floridians who live around the St. Johns River in eastern Florida were becoming optimistic that things were finally drying out. Residents were hoping repairs could get underway soon, but all of those plans were halted, and optimistic feelings were erased as yet another hurricane approached the state.

Hurricane Ian brought devastation to communities along the river in late September, including in Seminole County which is located northeast of Orlando. It took days before those living in Seminole County could even begin assessing the damage to their properties as water continued to pour into homes.

But right as the St. Johns River started to return to normal levels, Hurricane Nicole formed and brought yet another risk of flooding to the already devastated area. As Nicole approached the Florida coast, heavy rain once again returned.

Normally, the St. Johns River water level is about 2 feet at the river gauge in Astor, Florida, a Lake County community situated about 45 miles to the north of Orlando. When Nicole made landfall in Florida on Thursday, Nov. 10, the gauge there hit 4.5 feet, which is just 2 inches shy of the record flooding set just last month during Ian.

In general, the area saw a water level rise of about 1 to 1.2 feet after Nicole.

That may not sound like a lot, but it's such a flat landscape in that part of Florida that the rise was enough for the area to jump from moderate flooding back into major flooding, AccuWeather Senior Broadcast Meteorologist Geoff Cornish explained.
