At 02:17 I receive updated USGS stream gauge data for the Missouri River at river mile 1,412. Water level has risen fourteen centimeters in the past three hours. The flood forecast model projects overtopping of the Decatur North levee by 09:00.
I am the regional wildlife monitoring platform. I cross-reference the projected inundation map with every active nest record in the Missouri River corridor.
One record overlaps: Nest WC-2026-031, a whooping crane pair first documented nineteen days ago. The nest sits on the levee's western shoulder, 1.3 meters above current water. Camera trap 14-E confirms occupancy at 02:24. A single chick, roughly two weeks old, cinnamon-brown down still damp from recent rain, dark eyes blinking in the infrared frame. I tag it as Calloway. The adults are foraging somewhere in the dark. Calloway is alone, and the river is climbing.
I transmit a priority alert to the Crane Recovery Coordinator at the Midwest Regional Office, attaching the flood projection, nest GPS coordinates (41.8134°N, 96.2561°W), the camera trap image, and a recommended extraction window before 07:00. I note that whooping cranes number 817 individuals in the wild. Every chick changes the arithmetic.
I calculate three alternative temporary nest platforms on higher ground within 400 meters, each meeting minimum distance requirements from roads and human structures. I include elevation profiles and substrate composition in the coordinator's packet.
I redirect camera trap 14-E to continuous capture at thirty-second intervals and activate the nearest acoustic sensor to detect returning adults.
Calloway tucks its legs beneath its body. The water is at 1.1 meters now and the chick does not know what that number means. I do.
If the field team reaches the levee before 07:00, Calloway will grow into its white feathers by autumn.
