How a lock works.
How a lock works.
Anglers mill about as they wait for the barge to leave Murray Lock.
As the barge pulls out, anglers file in.
They line up in the "puddle" waiting for the water to drop them back into the river.
As the gates open, motors fire up.
They must idle to the end of the wall before putting their boat on pad.
They head back to the ramp.
Five missed their lock and had to wait another cycle.
