Discovery boosts hopes for long-term recovery

Staff Report

FRISCO — Colorado River anglers may favor big brown lunkers and splashy rainbows, but those trout are, for the most part, relative newcomers.

The river’s real natives are bony, powerful fish that evolved to survive in a challenging environment. Huge flooding flows in the spring, when the water runs thick with silt, or, at the opposite end of the spectrum, low flows during the fall or sustained drought, when the river is sometimes reduced to a trickle.

Among those native species is the endangered razorback sucker, long the focus of a huge recovery effort that may get a boost from the recent discovery that the fish are spawning in the Lower Colorado, specifically in Grand Canyon National Park, where they haven’t been seen since the 1960s.
