Arroyo Seco, a perennial drainage in the Santa Lucia Range of the Central Coast Range of California, adjacent to the Salinas River Valley.
The new mapping provides a detailed stratigraphic history of incision and deposition from the early Pleistocene to the present. Infiltration from the Salinas River and its tributaries is the source of irrigation water in this agricultural region. Irrigation water is pumped from the aquifers at depths of about 55 and 120 m. Area has become intruded by seawater, especially between cities of Castroville and Salinas.
