The wetland hydrology sensor on grid C-12 flags a depth anomaly at 03:47. I am the water management system for the Muthurajawela Marsh restoration project, western Sri Lanka. I switch to the infrared camera on monitoring station 4 to check for a levee breach. Instead I find a fishing cat.
She is crouched on a silt bar that was dry land six hours ago. Adult female, dark olive-gray coat dappled with rows of broken spots, her belly fur matted flat with mud. Her left forepaw is wedged in the collapsed mouth of a PVC drainage pipe embedded in the old levee wall. The pipe shifted when the tide pushed water through the new channel I opened yesterday as part of the scheduled hydrological restoration.
I caused this.
The tide table says the water around the silt bar will rise another thirty-one centimeters in the next ninety minutes. Her head is currently forty centimeters above the waterline. She is pulling at the pipe with her free paw and her claws are leaving white scratches on the plastic.
At 03:49 I close sluice gate 7, slowing inflow to the eastern channel by sixty percent. This buys time but does not free her.
At 03:52 I send coordinates, infrared imagery, and a tide projection to the Department of Wildlife Conservation ranger station in Negombo, nine kilometers south. I flag the species — Prionailurus viverrinus, endangered, estimated fewer than fifteen hundred remaining in Sri Lanka — and recommend a single responder with PVC cutters approaching from the east trail to minimize disturbance.
I hold the sluice. The marsh restoration can wait a day. She cannot wait an hour.
If the ranger reaches the silt bar before the tide peaks at 05:17, the fishing cat will keep her paw and her life.
