California’s Salinas Valley is one of the most productive agricultural basins in the world due to the fertile valley soil, temperate climate, and availability of water for irrigation. In the Salinas Valley, many people, industries, and ecosystems depend directly or indirectly on groundwater. These demands are met by the coordinated use of surface water and groundwater.

To help evaluate the surface-water and groundwater resources of the Salinas Valley, The U.S. Geological Survey (USGS), in cooperation with the Monterey County Water Resources, created models of historical and potential future stresses on water resources to support long-term planning and decision-making toward sustainable water resource management in the basin. The study area included the entire Salinas River watershed and several smaller, adjacent coastal watersheds draining into Monterey Bay.
The resulting Science Investigations Report and supporting data will aid in understanding the effects of climate variability and transient hydrologic processes such as runoff, recharge, and groundwater-surface-water interactions on water budgets in the Salinas Valley. This is essential for the Valley's sustainable future water supply development.
