As a polar vortex sweeps through much of the U.S., bringing icy conditions and snow to northern states, Florida is feeling the effects with colder coastal temperatures. This cold snap has prompted the state’s manatee population to seek out warmer waters, with one of their favorite spots being the warm-water outflows of power plants.

Known for their gentle nature and unique aquatic grace, these sea cows have been gathering in large numbers near Florida Power & Light Company’s Riviera Beach plant, where the company operates a public viewing attraction called Manatee Lagoon.

For decades, manatees have been drawn to the warm-water discharges from power plants located along Florida’s coast, especially during winter months when the temperature drops. The warm outflows from power plants provide a crucial source of heat, which helps the sea cows stay comfortable when natural waters become too cold.

Following a travel route passed down from mother to calf, these aquatic mammals, which can grow up to 10 feet (3 meters) long and weigh as much as 1,200 pounds (544 kilograms), have learned to migrate toward these warm waters.

The Manatee Lagoon attraction in Riviera Beach has become a popular destination for people wanting to observe these majestic creatures. Located near the Florida Power & Light plant, the two-story, 16,000-square-foot complex offers free public access, making it an ideal spot for both locals and tourists.

The educational center provides information on manatees’ role in the ecosystem and their unique behaviors. It also plays a crucial role in raising awareness about the challenges manatees face, including habitat loss, water quality issues, and the impact of cold weather events.

“Manatees are such a special species because they are a sentinel species,” said Rachel Shanker, education manager for Manatee Lagoon. “They are the first animals to respond to environmental changes, which makes them a key indicator of the health of our waters.” Due to their responsiveness to environmental shifts, manatees are invaluable for monitoring the state of Florida’s coastal ecosystems.

This year, as the cold snap continues, the manatees’ congregation near the Riviera Beach power plant has drawn increased attention. The public can observe these creatures up close at the Manatee Lagoon, which will host its annual ManateeFest on February 1, offering families the chance to learn about and celebrate Florida’s sea cows.

Manatee populations in Florida have been facing a number of environmental pressures in recent years, including a mass starvation event that significantly impacted the species. While they are still recovering, efforts like those at Manatee Lagoon play a vital role in their conservation, educating the public about the importance of preserving manatees and their habitats.

In addition to offering a fantastic viewing experience, the Manatee Lagoon serves as an educational hub, helping raise awareness of these gentle sea creatures and their role in keeping Florida’s coastal ecosystems healthy. As a sentinel species, manatees remain an essential indicator of the state’s environmental health, reminding us of the delicate balance that sustains Florida’s marine life.
