Rancho El Chorro (also called Rancho Cañada del Chorro) was a 3,167-acre (12.82 km2) Mexican land grant in present day San Luis Obispo County, California given in 1845 by Governor Pío Pico to business partners James (Diego) Scott and John (Juan) Wilson.
[1] The grant between Morro Bay and San Luis Obispo extended along the north bank of Chorro Creek.
James G. Scott (–1851), also a native of Scotland, came to California with his business partner Captain Wilson.
In 1845, Wilson moved his family from San Luis Obispo to Rancho Cañada de los Osos & Pacheco y Islay, built an adobe home and lived there until his death in 1860.
[6] With the cession of California to the United States following the Mexican–American War, the 1848 Treaty of Guadalupe Hidalgo provided that the land grants would be honored.
