San Anselmo Creek

[2] The Canada de Herrera, a 6,658-acre rancho that includes the areas that are now Fairfax, Sleepy Hollow, and part of San Anselmo, was granted to Domingo Sais in 1839.

[6] Historically, Corte Madera Creek watershed supported coho salmon (Oncorhynchus kisutch) with observations recorded from 1926 to 1927, the 1960s, 1981, and the last sighting in 1984.

[8] A spawning pair of Chinook salmon (Oncorhynchus tshawytscha) was observed by Michael Cronin just below Saunders Avenue in San Anselmo in 2003.

[6] River otter (Lontra canadensis) were photographed on the creek in 2007 despite not being listed as native to Marin County in Grinnell's 1937 Fur-bearing Mammals of California.

[1] In summer 2012 a partial fish passage barrier, the culvert beneath Center Boulevard in San Anselmo, is being modified with a fish ladder and concrete baffles, the latter to create resting places for migrating salmonids as they try to transit the high-velocity flows created by the concrete culvert.
