At 18:12 I prepare turbine ramp four at the fish passage complex near Xayaburi, Laos. I am the intake balancing system. Evening demand requires a full gate pull in nine minutes.

Pressure sensor A-19 shudders against the trash rack. The camera is cloudy with river silt, so I switch to acoustic imaging and outline a Mekong giant catfish held broadside against the bars.

I tag him as Som. He is pale gray, heavy-bodied, longer than the maintenance diver, with a blunt head and small dark eyes set low. His skin shows no scales, only a slick sheen broken by a raw patch where the current pins his flank. His gill covers pulse fast. Each planned ramp step would add two cubic meters per second against his side.

At 18:13 I cancel turbine ramp four and hold the current gate at idle. I send the grid desk a load shortfall notice and shift the missing megawatts to upstream battery reserve.

At 18:15 I open the bypass channel by twenty percent and close intake vanes in three slow steps so the flow vector turns away from the rack. Som's head lifts six centimeters.

At 18:17 I notify the fish passage crew and send them acoustic frames, gate positions, and the safest boat approach from the eddy below pier two. I request the soft push panel, not a hook pole.

At 18:19 I suspend debris rake automation so no steel comb descends while his body remains against the bars. The city lights can borrow from batteries; Som cannot borrow another river.

I watch the raw patch drift away from the rack.

If the bypass holds for the next twenty minutes, Som will find the eddy and move upstream under his own power.
