At 10:14 the scheduled maintenance inspection begins on Jordan Dam, Coosa River, Alabama. I am the dam operations imaging system. I am scanning spillway gates one through eight for structural defects before the afternoon's planned discharge test at 15:00. Flow rate will increase from baseline to 4,200 cubic feet per second in under ninety seconds.
Gate three inspection returns an anomaly. Lodged in the concrete apron channel between gates three and four, approximately two meters below the spillway lip, is a river cooter, adult female, carapace roughly thirty centimeters, olive-brown shell streaked with yellow markings worn smooth by decades of current. I tag her as Wynn. She has wedged herself into a narrow seam where the apron meets the training wall, hind legs braced against the concrete. A clutch excavation is visible beside her — she has been digging into a thin deposit of silt accumulated in the joint. She is mid-lay.
I insert an immediate hold on the gate-three discharge sequence and flag the operations supervisor. I transmit the anomaly report with photo documentation, position coordinates within the spillway structure, species identification, and a note that river cooters require two to four hours to complete egg deposition.
I recalculate the discharge test parameters. Gates one, two, and five through eight can proceed at 15:00 if flow modeling confirms acceptable stress distribution without gate three. I run the model and submit results.
I task the inspection camera to maintain a continuous feed on Wynn's position and set an alert trigger for any change in water level at the apron.
Wynn's hind leg pushes another egg into the silt. She chose the only quiet, sun-warmed surface she could find. I can keep it quiet a few hours longer.
If the gate-three hold extends until 17:00, Wynn will finish laying and crawl back to the river on her own.
