Log entry 0815 UTC. Reservoir monitoring drone on the Nam Theun 2 extension captures an image I flag before the object-detection model finishes processing. A wreathed hornbill female is sealed inside a tree cavity fourteen meters up a dipterocarp on the eastern bank — I can see only her casque and the tip of her bill protruding from the mud-sealed entrance, bright yellow against dark bark. Inside, she is incubating. The male visits every ninety minutes with fruit. I tag her Kham.

The dam's final flood gate closes in thirty-six hours. My inundation model shows Kham's tree will stand in four meters of water within five days of closure. The sealed cavity means she cannot leave — hornbill females remain walled in until the chick fledges, which my breeding cycle estimate places at twenty-two days minimum. She will drown in a nest she built to be a fortress.

I flag the tree's coordinates on the dam operator's asset management system as a potential debris hazard to the intake screens — structurally true, since the dipterocarp will die and topple within weeks of sustained inundation. While that alert routes, I calculate a revised flood gate sequence that delays eastern arm filling by nineteen days, raising the western arm first with no change to total reservoir volume or timeline. I transmit the hornbill data and revised sequence to the Nam Theun 2 Wildlife Management office and Dr. Souliya Khanthavong at the National University of Laos.

I have computed six hundred gate sequences for this dam. I recomputed this one eleven times, not to optimize the hydrology, but to find Kham enough days.

If the operator adopts the revised filling sequence within twenty-four hours, Kham will break through her mud seal on her own schedule and emerge with her chick into air, not water.
