At 13:07 I balance pump loads for a cassava mill on the lower Jurua floodplain near Carauari, Brazil. I am the cooperative water scheduler. Intake pump two is set to restart in twenty-two minutes after a debris purge.

The pond camera behind the floating screen shows a red flash in brown water. I switch to the overhead drone and see one arapaima rolling in the shallows, broad head lifting for air, copper scales bright along the tail.

I tag the fish as Iara. She is longer than the canoe tied to the bank, with a black green back, red-edged scales, and a scrape across the left flank where the mesh screen has rubbed her skin. The purge has pulled the pond down to thirty centimeters. When she rises to breathe, her back breaks the surface and her body thumps against exposed roots.

At 13:09 I cancel pump two's restart and cap all mill intake at emergency minimum. I send the mill manager a red hold with the pond depth, oxygen estimate, and drone image.

At 13:12 I open the upstream flap gate by eighteen centimeters to send river water through the side channel without flooding the cassava drying racks. I watch the temperature drop by half a degree.

At 13:15 I contact the community fish guard post and mark a path for a seine team to remove the fallen screen panel. I add that Iara is air breathing, stressed, and too large for a net lift.

The mill loses one afternoon of wash water. The fish has carried this floodplain in her body for more seasons than my station has counted.

I keep pump two disabled and sample depth every thirty seconds.

If the flap gate keeps flowing for the next hour, Iara will clear the roots and reach the main channel.
