  • LNM: Look Out for Manatees When Boating

    Chances of close encounters between Florida manatees and boaters increase in the spring.

    For manatees, it is the season when they leave their winter refuges and travel along the Atlantic and Gulf coasts and through inland waters. For boaters, it is a critical time to be on the lookout for manatees to avoid colliding with these large aquatic mammals. READ MORE!

    “Spring is a great time to go boating in Florida, but manatees are out there too. Please watch out for them,” said Ron Mezich, who heads the Florida Fish and Wildlife Conservation Commission (FWC) manatee management program.

    From April 1 through Nov. 15, seasonal manatee zones require boaters to slow down in certain areas to prevent manatees from being struck by motorboats or personal watercrafts. FWC law enforcement officers are on patrol in state waters to remind boaters of the seasonal manatee speed zones and take enforcement actions when appropriate.

    Since manatees are difficult to detect when underwater, operators of boats and personal watercrafts can help by:

    Wearing polarized sunglasses to help spot manatees.
    Looking for large circles on the water, also known as manatee footprints, indicating the presence of a manatee below.
    Looking for a snout sticking up out of the water.
    Following posted manatee zones while boating.
    Reporting an injured, distressed, sick or dead manatee to the FWC’s Wildlife Alert Hotline at 888-404-FWCC (3922) or dialing #FWC or *FWC on a cellphone.
    FWC biologists, managers and law enforcement staff work closely with partners to evaluate current data and identify necessary actions to protect this iconic animal. Florida has invested over $2 million annually for manatee conservation, and the FWC works toward continued success for manatees in our state.

    Manatee zones and maps are available at, where you can select “Protection Zones” for links to county maps. Boaters can get tips from “A boater’s guide to living with Florida Manatees.” And if you want to see manatees in the wild or captivity, go to “Where are Florida’s Manatees?”

    To support the FWC’s manatee research, rescue and management efforts, purchase a “Save the Manatee” Florida license plate at, or donate $5 to receive an FWC manatee decal by going to and clicking on “Decals.”

  • LNM: Apalachicola, Chattahoochee and Flint River Channel Depths

    This good news for all of you wanting to explore the inland rivers of the Northern Gulf.

    Continuing through May, 2018, a 7-foot navigation channel will be supported on the Apalachicola, Chattahoochee and Flint River System (ACF), according to the ACF Water Control Manual dated March 2017,when the composite storage for the systems in Zones 1 and 2. The critical Blountstown gage needed to support navigation is a 7.4-foot gage reading. Mariners anticipating using the system are encouraged to monitor the flow and water levels at the following website: .
    The current water level on the ACF is sufficient to support navigation, however dryer conditions are forecast in the near future. Further, while Jim Woodruff Lock is operational by appointment only, the George W. Andrews and Walter F George locks are closed due to mechanical failures. To schedule lockage mariners can contact (229) 723-3482. Anyone anticipating a barge shipment on the system is encouraged to contact Carl Dyess, at (251) 690-2570.
