John Day dam avian predation (#0347)

John Day dam avian predation (#0347)
If you look in the upper right corner and then look towards the left, you can barely see a grid of very thin wires that are vertical in the picture. These are designed to keep birds away from the seabound smolt departing the outflow on the lower right.
