The Chumash laborers built a connection between the canyon creek and the Santa Barbara Mission water system through the use of a dam and an aqueduct. It was dedicated by Padre Fermín Lasuén, who succeeded Padre Junipero Serra as the second president and founder of the California Franciscan Mission Chain. It was the tenth of the California Missions to be founded by the Spanish Franciscans. The Santa Barbara Mission was established on the Feast of Saint Barbara, December 4, 1786. Many of the Spaniards brought their families with them, and those formed the nucleus of the small town – at first just a cluster of adobes – that surrounded the Presidio of Santa Barbara. They were sent to both secure the Spanish claim to the region and to convert the indigenous peoples to Catholicism.
The first permanent European residents were Spanish missionaries and soldiers under Felipe de Neve, who arrived in 1782 and constructed the Presidio.
