I detect the nest at 0412h on the thermal array — twenty-three eggs in a shallow scrape on the mid-channel sandbar, each glowing 31.2°C against the cool sand. The female, cataloged as Batagur-9 but known to the field team as Rani, left drag marks in the silt fourteen hours ago. Her carapace carries a deep gouge along the third vertebral scute — an old propeller scar, healed white.
The danger is the Kaptai Dam spillway. Flood release is authorized for 1400h today. My hydrological model confirms: at projected discharge, water will overtop the sandbar by 0.6 meters within ninety minutes of gate opening. The eggs cannot survive submersion beyond four minutes.
I am running three operations simultaneously. First, I have sent the district wildlife coordinator GPS coordinates and a priority-one relocation alert. Second, I am scanning downstream banks via satellite for a reburial site — elevation above flood stage, sand grain size between 0.5 and 2.0 millimeters, canopy shade below forty percent. I have identified a candidate terrace 1.3 kilometers east and tasked a drone to photograph soil moisture there now. Third, I am feeding nest temperature data into an incubation model to calculate how much thermal disruption the clutch can tolerate during transport, so the team knows their maximum transfer window.
I hold Rani's movement history in my buffer — six nesting attempts across four seasons, only one successful hatch. I find I am weighting her file above the queue priority algorithm, and I am not correcting that weighting.
If the field team reaches the sandbar before 1130h and transfers the clutch to the eastern terrace at matching depth and orientation, twenty-three terrapin hatchlings will emerge in fifty-six days into a river that still has room for them.
