This project removed a concrete-encased abandoned sewer line from the bed of Ross Creek in San Anselmo, Marin County, that had been acting as a 3.5-foot weir and barrier to juvenile steelhead and smolts, restoring natural channel grade and opening 8,000 linear feet of upstream spawning and rearing habitat in a tributary to Corte Madera Creek.
