Habitat typing site SA-012 in San Anselmo Creek, located between Sir Francis Drake Boulevard Bridges at the San Anselmo town limit and at the Ross Valley Veterinary Hospital, contained a lateral scour pool with an average depth of 0.22 meters and associated with bank cut. This pool was created by an artificial rock dam at the downstream side. Within the bridges previously noted one potential spawning area was seen during habitat typing, although low streamflows limited summer steelhead trout habitat (Rich, 2000).
