Abstract: This report is in partial response to authorization and appropriations provided in the Energy and Water Development Appropriation Act of 1994 (P.L. 103-126). The results of engineering and environmental studies are presented for the implementation of the Manatee Protection Plan, Part II at seven selected sector gate locks in Central and Southern Florida. As a response to recent manatee mortality trends associated with water control structures, the purpose of the project is to provide operational changes and implement the installation of a manatee protection system at locks. The beneficial outcome of this project will be the reduction of risk, injury, and mortality of the manatee which is an endangered species in Florida. The recommended plan is to install manatee detection systems on the sector gates at navigational locks. Hydroacoustic and pressure sensitive devices will immediately stop the gates when an object is detected between the closing gates. These systems will transmit an alarm and signal to stop the gate movement when a manatee is detected. When the gate sensors are activated by an object or manatee, the gate will stop and open approximately six inches to release a manatee. As a result, a manatee will be able to travel between the open gates. After the gate opens, the operator can fully close the gate unless an object remains between the gates. Then, the opening process will repeat the cycle as the sensors are activated again. Due to these structural modifications, manatees will be at a significantly less risk as they encounter sector gate locks. The project modification has a total estimated cost of $2,007,000. The Federal and non-Federal costs for the recommended plan are $1,811,000 and $196,000, respectively.
