One of its last holdouts is in the Grand Canyon section of the Colorado River at a major tributary, the Little Colorado. Glen Canyon Dam took its toll on the little fish, and by the late 1990s, its population plummeted to a few thousand.

But these days, the humpback chub appears to be making a comeback.
