Ever wonder how some wildlife departments stock the rivers and lakes?

In Oregon, the Department of Fish and Wildlife are using helicopters and flying in 350,000 trout in more than 450 Oregon lakes, all via airdrops. Flying in will be young rainbow, brook and cutthroat trout.

The helicopters hold canisters of fish which are then opened at released from a hundred feet up.

The DFW justifies the expense of the helicopters, around $2 grand an hour, due to the fact that Oregonian waters are known for trout fishing.
