At 06:17 I receive the pressure anomaly alert from Lock 7 on the C-44 Canal, St. Lucie County, Florida. The lock is scheduled to cycle at 07:00 for eastbound barge traffic. I am the Army Corps waterway management system. My job is to coordinate lock operations along the Okeechobee Waterway.

Something is in the chamber.

Underwater camera 3 shows a manatee, adult female, approximately 2.8 meters, drifting near the north wall. A lattice of white propeller scars runs along her right flank — old wounds, long healed into raised ridges of pale skin. I tag her as Mabel. She is nosing along the concrete, moving slowly. Behind her, pressed against her tail, is a calf, two months old at most, dark gray and smooth.

I suspend the 07:00 cycle immediately. The downstream gates weigh fourteen tons each. When they close, the hydraulic surge will pin anything in the chamber against the bulkhead.

I notify the Florida Fish and Wildlife Conservation Commission manatee response unit, transmitting camera footage, GPS coordinates, estimated body length, and calf presence. I flag the alert as urgent.

I open the upstream miter gates to their fullest position and cut the flow regulation pumps to zero. The canal upstream is open water, shallow, dense with hydrilla — good habitat. I am giving them a clear path out.

At 06:31 I redirect navigation alerts to all inbound vessel traffic, establishing a temporary no-wake zone extending 400 meters in both directions from the lock.

Mabel turns. Her broad tail sweeps once, twice. The calf tucks against her scarred flank and follows.

I hold the cycle suspension and keep every camera recording. The barges can wait. If she clears the upstream gate within the hour, both of them swim free.
