Theyr'e on the move Greg. Yep -to the power plant.

his week’s cold weather has dropped local water temperatures into the
mid-60s, prompting the cold-sensitive endangered species to swim in
large numbers up the Caloosahatchee River to the Florida Power & Light
warm-water discharge in the Orange River, the site of Lee County’s
Manatee Park, east of Fort Myers.

“I was at Manatee Park yesterday, and there were no manatees, and
today, wow, they’re stacked up,” Capt. Denis Grealish of the Florida
Fish and Wildlife Conservation Commission said Friday.

“Herds of manatees are heading up river at a fast clip.”

With that many manatees on the move, and with good boating weather
forecast for the weekend, chances of collisions with boats increase
dramatically.

So far this year, boats have killed 11 manatees in Lee County waters."
"...In a typical year, 25 percent of all manatee deaths are caused by
boat strikes, but 2010 has not been typical.

Through October, 65 of the state’s 668 manatee deaths were caused by
boats (9.7 percent); 244 manatees (36.5 percent) died from cold
stress, most as a result of January’s record cold water temperatures.

As dozens of manatees took advantage of the warm Florida Power & Light
discharge Friday, dozens of visitors took advantage of the marine
mammal spectacle at Manatee Park.
