"Biologists and engineers are setting the stage for an environmental recovery effort in downtown Los Angeles that could rival the return of the gray wolf, bald eagle and California condor.

This time, the species teetering on the edge of extinction is the Southern California steelhead trout and the abused habitat is a 4.8-mile-long stretch of the L.A. River flood-control channel that most people only glimpse from a freeway.

The brutal vista of concrete and treated urban runoff exists as an impenetrable barrier to ancestral spawning grounds in the San Gabriel Mountains for the estimated 400 federally endangered Southern California steelhead left on Earth.

The Los Angeles River Fish Passage and Habitat Structures Design Plan, which is being championed by Mayor Eric Garcetti, aims to change all that with a carefully calibrated retrofit."
