1988 - Simulated Effects Of Groundwater Management Alternatives For The Salinas Valley, Water Resources Investigations Report 87-4066 Apr 2018

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 …


1974 - Geology Of The Southern Salinas Valley Area, California Apr 2018

1974 - Geology Of The Southern Salinas Valley Area, California

State and Federal Documents Relating to Monterey and San Luis Obispo Counties

This 1974 report about the geology of the southern Salinas Valley was concerned mainly with relating the occurrence of petroleum and other mineral commodities to the Cenozoic history of the area. The investigation had two phases. First phase involved detailed geologic mapping of quadrangles that cover most of Tertiary beds west of the Salinas River. Second phase included a reconnaissance geologic mapping to extend the results of the first phase to a larger area. The report summarizes results of the geologic investigation of the entire southern Salinas Valley area.


1978 - Water Resources Investigations - Two-Dimensional And Three-Dimensional Digital Flow Models Of The Salinas Valley Ground-Water Basin, Report 78-113 Apr 2018

1978 - Water Resources Investigations - Two-Dimensional And Three-Dimensional Digital Flow Models Of The Salinas Valley Ground-Water Basin, Report 78-113

State and Federal Documents Relating to Monterey and San Luis Obispo Counties

This 1978 report discussed a group of hydrologic models that were developed for the Salinas Valley that included the small-stream model, river model, two -dimensional ground-water model, and three dimensional ground-water model. The small-stream model simulated ground-water recharge from small streams that were tributary to the Salinas River. The river model simulated ground-water recharge from and surface-water discharge in the Salinas River. The two-dimensional and three-dimensional ground-water models simulated hydraulic head in the ground-water basin. The report noted that in addition to being an important agricultural area, Salinas Valley contained several growing urban areas that obtained water from the ground …


1965 - Dwr Bulletin No. 130-63, Hydrologic Data, Volume Iii, Central Coastal Area Apr 2018

1965 - Dwr Bulletin No. 130-63, Hydrologic Data, Volume Iii, Central Coastal Area

State and Federal Documents Relating to Monterey and San Luis Obispo Counties

This bulletin is a report on surface water, groundwater and climate in the Central Coast Area of California for the period October 1, 1962 through September 30, 1963. It includes a text that summarizes hydrologic conditions in this region and contains five appendices: Appendix A, Climate; Appendix B, Surface Water Flow; Appendix C, Ground Water Measurement; Appendix D, Surface Water Quality; and Appendix E, Ground Water Quality.


1970 - Geology Of Southern Monterey Bay And Its Relationship To The Groundwater Basin And Salt Water Intrusion Apr 2018

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 …

1958 - Dwr Bulletin No. 18, San Luis Obispo County Investigation, Volume Ii, Appendixes

State and Federal Documents Relating to Monterey and San Luis Obispo Counties

This 1958 document contains the agreement and supplements between California State Water Resources Board, San Luis Obispo County and the California Department of Public Works; a discussion concerning the geology and groundwater in San Luis Obispo County; as well as records of precipitation, daily runoff and miscellaneous stream flow measurements, depths of groundwater, mineral analyses of surface and groundwater supplies, applications to appropriate water, soil moisture depletion, plans for the protection and development of recreational resources, and alternative plan of development of Nacimiento and San Antonio Rivers.


2015, November - Salinas River Salt Modeling Report , Tetra Tech For California Central Coast Regional Water Quality Control Board And Us Environmental Protection Agency, Region Ix Jul 2017

2015, November - Salinas River Salt Modeling Report , Tetra Tech For California Central Coast Regional Water Quality Control Board And Us Environmental Protection Agency, Region Ix

State and Federal Documents Relating to Monterey and San Luis Obispo Counties

Report prepared by Tetra Tech on behalf of California Central Coast Regional Water Quality Control Board and US Environmental Protection Agency, Region IX with a view of development of salt-related TMDLs and a salt and nutrient management plan for the Salinas Valley aquifers. The report provides data analysis and a literature review, development of a water and salt mass balance tool, and salt sources assessment. Recommendations regarding improved representation of cropland locations, rotations, and irrigation practices are provided.
