Rancho San Jose del Valle
Rancho San Jose del Valle (also called "Rancho Agua Caliente" or "Warner's Rancho") was a 26,689-acre (108.01 km2) Mexican land grant in present-day San Diego County, California given in 1840 by Governor Juan B. Alvarado to Jose Antonio Pico, and then given in 1844 by Governor Manuel Micheltorena to Juan Jose Warner. The most northeasterly grant made within present-day San Diego County, it was bounded on the west by Palomar Mountain, and on the south by Buena Vista Creek and Rancho Valle de San Jose, and encompassed present-day Warner Springs. The western part of the grant is under the waters of Lake Henshaw, formed in 1922 by a dam on the San Luis Rey River.
In 1840, Governor Alvarado granted José Antonio Pico, whose brother Andrés Pico was then administrator of the mission, made formal application for "the place called Agua Caliente", belonging to the Mission San Luis Rey. Continued trouble with the Indians probably caused Pico to abandon the land.
Jonathan T. Warner (1807-1895), better known as Juan José Warner, was in born in Connecticut. He settled at Los Angeles in 1831 and in 1836 married Anita Gale, daughter of a Boston sea captain, who had been brought to California when five years of age and placed in the care of the Pico family, by whom she was adopted. In 1844, Governor Micheltorena granted the six square league Rancho San Jose Del Valle to Juan José Warner.
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. As required by the Land Act of 1851, a claim for Rancho San Jose del Valle was filed with the Public Land Commission in 1852, and the grant was patented to Juan J. Warner in 1880. A claim by Juan J. Warner for four more square leagues (Rancho Camajal y Palomar) west of Rancho San Jose del Valle was rejected.
