Latest Manatee Update: January 24, 2017 I was expecting the river temp to be lower than the 68° F (20° C) it was. Then I was surprised to find 39 manatees. I paddled out to the river and Howie swam in under the canoe. Then when I reached the main observation deck, I found Rocket had finally made it home from the spring to our north. He has a new scar, but he is okay. Photo is Rocket from today. -- Wayne Hartley, Manatee Specialist.
