[4] Salsipuedes Creek is the lowermost tributary of the Pajaro River, which carries its waters to Monterey Bay and the Pacific Ocean.

They stopped to camp near a lagoon in the middle of a narrow valley which Father Crespi named Santa Teresa.

The upper watershed of Corralitos Creek and its Browns Creek tributary is designated "high potential" habitat for steelhead trout (Oncorhynchus mykiss) and is a top priority stream for the protection and restoration of the South-Central California Coast Distinct Population Segment (DPS) of this anadromous fish.

[12] Citizen naturalist and author William "Bill" Leikam reported Chinook salmon (Oncorhynchus tshawytscha) and steelhead trout in Corralitos Creek while fishing in the reach along Freedom, California at the season's first large winter storms through the 1950's.

[13] This is consistent with a 1912 report by Stanford University ichthyologist John Otterbein Snyder of Chinook salmon (Oncorhynchus tschawytscha) in the Pajaro River watershed.
