Watch These Trout Run the Fish Ladder Gauntlet

Dams can cause some serious problems for fish, who can’t pass through to their traditional spawning grounds through a massive wall of concrete. The “solution” is a fish ladder, which is an elaborate maze that fish have to negotiate in order to get over the dam. In this video, we watch as a few trout successfully navigate through the man made ladder, up into a fish elevator, and then out into the water above.
