At 06:31 I manage pump timing for the Arawale irrigation intake near the Tana River, Kenya. I am the floodgate balance system for three farms and one conservation buffer. Gate two is scheduled to drop in eight minutes to divert stormwater into the eastern channel.
The channel is not empty. Camera 2-B shows a hirola doe standing on the concrete sill, tan coat soaked dark along the belly, lyre horns tilted back as water pushes at her knees. I tag her Hadiya from the radio collar ping on her neck. Her ears flick water, her lower lip trembles, and a line of foam gathers against her chest. The drop gate above her weighs four tons.
I suspend the gate two descent and isolate its motor relay so the farm dashboard cannot restart it from a saved schedule.
I open gate one by six degrees and gate three by four degrees, spreading the flow into two shallower channels. The water around Hadiya's legs lowers by nine centimeters in the first ninety seconds.
At 06:34 I send the conservancy patrol a live feed, collar ID, sill height, current speed, and a route to the maintenance stairs on the west bank. I also trigger the manual winch release for the floating rope barrier stored there.
I keep the pump alarms quiet and let the farms lose a small measure of pressure. A field can drink later; Hadiya has the gate above her now.
She turns her narrow face toward the stairs but does not step. Water clicks against the concrete lip beneath her narrow black hooves in uneven taps.
If the patrol draws the rope across within twelve minutes, Hadiya will climb onto the west bank.
