History

There is considerable evidence of human inhabitation of the area currently known as Lake San Marcos long before the Spanish establishment of the Mission San Diego de Alcala in A.D. 1769. Native American tribes lived and flourished near the San Luis Rey River in the Late Prehistoric period. Much of this area was originally part of Rancho Los Vallecito de San Marcos. On April 22, 1840, Governor Juan Bautista Alvarado granted the 8,877-acre Rancho Los Vallecitos de San Marcos to Don Jose Maria Alvarado who married Lugarda Osuna, daughter of the owner of San Dieguito Rancho, Don Juan Maria Osuna.
