Chinook
Fall-run Chinook salmon have been observed in the Napa River in recent years (Jones 1999, as cited in NMFS 1999; Leidy and Sisco 1999), upstream to the base of the Kimball Canyon Dam north of Calistoga (Leidy and Sisco 1999). Fall Chinook returns to the Napa River are thought to be small and sporadic, with only occasional observations of spawning primarily between Zinfandel Lane, slightly downstream of St. Helena, and the City of Calistoga (Leidy and Sisco 1999; S. Anderson, pers. comm., 2000; Emig, pers. comm., 2000; Rugg, pers. comm., 2000). The National Marine Fisheries Service believes that these populations are not self-sustaining and likely consist of strays from other basins and are more likely present only on an intermittent basis during favorable periods (NMFS 1999).
