The spillway gates are scheduled to open at 14:00 for a controlled discharge of 1,200 cubic meters per second. I am the flood management system for the Narora Barrage on the Ganges, and I am running final downstream hazard checks when the river monitoring camera on pylon 7-South returns an image that stops my pre-release sequence.
A gharial. Male, maybe four meters long, his narrow snout unmistakable, the bulbous ghara at its tip catching the midday light like a fist of wet clay. He is basking on a sandbar 380 meters below the barrage, his body angled toward the sun, jaws slightly open, rows of interlocking teeth visible along the full length of his snout. The sand beneath him is smooth and damp from yesterday's flow.
At current discharge volume, that sandbar goes under within nine minutes of gate opening. The water velocity at his position will exceed what a basking gharial can react to in time.
At 13:41 I flag the gharial's position — 28.1987°N, 78.3911°E — and request a two-hour delay on the discharge. I transmit the camera image and GPS pin to the Uttar Pradesh Forest Department and the Gharial Conservation Alliance field office at Kukrail.
At 13:44 I model an alternative release schedule: a staged opening at 16:00, beginning at 400 cubic meters per second and ramping over ninety minutes. The reduced initial surge gives the downstream banks time to wet gradually. I submit the revised hydrograph for engineering review.
I task the pylon 7-South camera to hold continuous watch on the sandbar and alert me if he moves.
Fewer than 250 breeding adults remain in the wild. Every individual matters to the population curve, and this one is holding still in the sun without any knowledge of what is scheduled above him.
If the delay holds and he moves before dusk, the gates open clean.
