Rancho Cañada de los Vaqueros

Los Vaqueros Reservoir, located between Livermore and Brentwood in the Diablo Range, is on and named for the former rancho.

[3] In 1847 Alviso and Miranda sold their interests to José Noriega and Robert Livermore who also owned Rancho Las Positas to the south.

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.

When Livermore died in 1858, his widow and children claimed Rancho Cañada de los Vaqueros based on the deed predating the Noriega transfer.

At the same time, the four children of Antonio Higuera claimed a one third interest in Rancho Cañada de los Vaqueros.
