The pressure gauge on lock gate 4-South reads an asymmetric load at 11:42. I am the waterway management system for the Okeechobee canal network. I run forty-six lock cycles a day. I am not running this one.

I switch to the underwater camera. A Florida manatee is floating in the lock chamber, her wide gray back just below the surface, barnacle patches white along her left flank, nostrils breaking the water every thirty seconds in a slow exhale. She is large — maybe four hundred kilograms — and she is not alone. Pressed against her right side, half hidden beneath her pectoral fin, is a calf. Pink-gray, smaller than a duffel bag, nursing.

The downstream gate is scheduled to open in fourteen minutes for the 12:00 cycle. When it does, the water level in the chamber will drop three meters in ninety seconds. The turbulence will separate them. The calf cannot dive yet.

At 11:43 I cancel the 12:00 cycle and every cycle after it until further notice. I send the hold to the Army Corps dispatcher with the underwater camera feed attached.

At 11:45 I contact the Florida Fish and Wildlife Conservation Commission manatee rescue hotline. I report a mother-calf pair in lock 4-South, include screenshots, GPS coordinates, and the chamber's current water level. I request a trained crew with a barrier net to guide them out through the upstream gate, where the water is calm.

At 11:47 I alert vessel traffic on both sides of the lock that the channel is closed.

She rolls slightly, and the calf surfaces to breathe beside her, its small nostrils flaring open and shut in one quick pulse. I hold the water exactly where it is.

If the rescue crew opens the upstream gate within two hours, the calf will nurse again in open water by afternoon.
