The goals of this $2.7M Herring Passage and Smelt Habitat Restoration project were to: replace the existing fish diversion gate at the tunnel outlet with a more effective design that will prevent fish from entering the tunnel; re-establish substrate suitable for smelt spawning on the concrete pad downstream of the tunnel outlet and fish ladder; restore a resting pool for river herring immediately downstream of the concrete pad; and regrade an unauthorized rock weir downstream of the concrete channel to restore flow depths and velocities suitable for smelt spawning.

JTC’s scope of services included materials testing and inspection of the following: concrete, grout, and soils.
