1998 - Salinas Valley Water (Preliminary Analysis Of) The Cause And Cost Of Seawater Intrusion
1998 - Salinas Valley Water (Preliminary Analysis Of) The Cause And Cost Of Seawater Intrusion
Miscellaneous Monterey and San Luis Obispo County Documents and Reports
An analysis of the historical cause of seawater intrusion in the Pressure Area of Monterey County. An annual overdraft of groundwater resources near the coast coupled with a seasonal cycle of over pumping created a reversal in the groundwater gradient and associated cones of depression. "Marine intrusion has occurred in the 180-foot aquifer in recent years as a result of overdrafts." (Bulletin 52, 1946, p.27). The only overdrafts on groundwater in the Salinas Valley were in the East Side and Pressure Areas. "There was no shortage of groundwater in the remainder of the basin and no threat of deficiency under …
2014 - Quarternary Geologic Map Of North-Central Salinas River Valley And Arroyo Seco
2014 - Quarternary Geologic Map Of North-Central Salinas River Valley And Arroyo Seco
Miscellaneous Monterey and San Luis Obispo County Documents and Reports
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.
1988 - Simulated Effects Of Groundwater Management Alternatives For The Salinas Valley, Water Resources Investigations Report 87-4066
State and Federal Documents Relating to Monterey and San Luis Obispo Counties
This 1988 investigation was done by the U.S. Geological Survey in cooperation with the Monterey County Flood Control and Water Conservation District. The purposes of this study were to identify and quantify the various types of flow into and out of the ground-water basin and to describe the physical processes that control them. The hydrologic analysis included development of a two-dimensional digital flow model. One of the goals of the study was to update and improve a previous digital model of the basin. The report noted that because of the proximity of Salinas Valley to the ocean, large rates of …

1970 - Geology Of Southern Monterey Bay And Its Relationship To The Groundwater Basin And Salt Water Intrusion
State and Federal Documents Relating to Monterey and San Luis Obispo Counties
This report discussed the preliminary results of a U.S. Geological Survey and the State of California joint investigation of Monterey Bay. The objective of the survey was to delineate the groundwater basin offshore, to determine the distribution and locations of fresh water aquifers by locating areas in the Monterey Submarine Canyon and the ocean bottom in Monterey Bay where aquifers might outcrop and thus be areas of entrance for seawater. The report noted that since the early 1940s continuous heavy pumping along the coastal area of the Salinas Valley had depleted the groundwater storage and lowered the piezometric levels to …
1995 - Hydrogeology And Water Supply Of Salinas Valley, White Paper By Salinas Valley Ground Water Basin Hydrology Conference
Monterey County Water Resources Agency Water Reports
The solution to the water resource problems within the Salinas Valley had been known since at least 1946. The best solution, proposed at that time by the California Department of Water Resources (DWR), recognized that sufficient supplemental water could be developed within the basin recognizing the need to transfer water from the Forebay Area to the Pressure and East Side areas. The Salinas Valley Ground Water Basin Hydrology Panel urged Monterey County Water Resources Agency to focus on completion of the extraction facilities and conveyance system similar to those outlined in the DWR Bulletin 52 in 1946; to continue studies …
2004 - Final Report, Hydrostratigraphic Analysis Of The Northern Salinas Valley
2004 - Final Report, Hydrostratigraphic Analysis Of The Northern Salinas Valley
Miscellaneous Monterey and San Luis Obispo County Documents and Reports
The Monterey County Water Resources Agency (Agency) is responsible for the management and planning of water resources within Monterey County The agency uses a network of wells to monitor groundwater conditions in the Salinas Valley ground water basin (Figure 1). The progressive advancement of the seawater intrusion front into groundwater zones and the understanding of the northern Salinas ground water basin hydrogeology have been documented by the Agency since the 1950s. Only since the late 1990s was there sufficient well logs, geophysical, and lithological data to support a three-dimensional (3-D) study of the inter-related ancestral fluvial and alluvial-fan depositional environments …
