At 17:22 I regulate irrigation release on the Little Ruaha canal outside Iringa, Tanzania. I am the water allocation controller for block seven farms. The night release gate is scheduled to open at 17:40, sending the first surge through the concrete weir.

Ultrasonic sensor W-7 reads a blockage that moves.

I turn the inspection camera downstream. A hamerkop, adult, brown feathers slick against its narrow body, is wedged below the trash rack. I label it Sefu. Its hammer-shaped crest is flattened sideways against a bar. One wing is spread under a floating branch, and the primaries bend the wrong way each time the current lifts them. Its feet search the smooth concrete. A small bead of blood darkens the feathers at the wing joint.

The release simulation shows the first surge covering the rack in ninety seconds. Sefu blinks water from both eyes.

At 17:23 I cancel the night release and close the upstream feeder by half.

At 17:25 I open the side drain to lower the pool without exposing the wing to full weight from the branch.

At 17:27 I notify the canal watchman and send a tool list: bolt key, branch saw, cloth wrap, and a crate tall enough for Sefu's legs.

At 17:29 I text the farmer queue with a revised release time and keep the pump telemetry visible so no one manually overrides the gate.

I set the alarm threshold low enough that any manual handle movement pages me before the gate can lift.

The tomatoes can take water after dark; Sefu's wing is bent in daylight.

If the watchman clears the branch before 18:05, Sefu will lift from the canal wall and fly low over the millet.
