2017 – The Development Of The Land Tenure And Water Systems In California And Specifically In The Salinas Valley Groundwater Basin [Draft]
Related Research and Documents
Beginning with the Aboriginal era through the Spanish, Mexican and United States eras, maps and governmental documents reflect the state of knowledge concerning California (and the Salinas Valley) along with the driving needs and policies that determined how water was used and managed. By examining the maps, it is possible to determine the state of knowledge in Europe (and later in the United States) as it related to the physical and geographical attributes of California prior to colonization and subsequently throughout the Spanish and Mexican periods. Governmental documents provide a window to how land was used and granted during the …

2015 – Project Justification – Addressing An Urgent Water Supply Need For A Disadvantaged Community In The Greater Monterey County Irwm Region
Miscellaneous Monterey and San Luis Obispo County Documents and Reports
One hundred percent of Castroville’s water supply comes from the 400-foot aquifer of the Pressure sub-basin of the Salinas Valley Groundwater Basin. Groundwater levels in the aquifer dropped more than 100 feet below the seal level as of July 2015 at static conditions. Water levels dropped to more than 190 feet below the mean sea level during operation of the water well. The dramatic drop combined with the close proximity of the Pacific Ocean (less than 4 miles) and to existing seawater intrusion (less than ¼ mile) raised significant alarm that the existing water supply system to Castroville was imminently …
2013, November 19 - Protective Elevations To Control Sea Water Intrusion In The Salinas Valley, Geoscience For Mcwra
Miscellaneous Monterey and San Luis Obispo County Documents and Reports
A report prepared in support of preventing revocation of Permit 1043 (State of California Division of Water Rights Permit for Diversion of Use of Water – Amended Permit 11043 dated 110-Jul-49) that allows for appropriation of water from the Salinas River in Monterey County California not to exceed 400 cfs with annual maximum diversion not to exceed 168,538 acre feet per year. The report addresses the potential beneficial uses of diverting water to help increase groundwater levels in the Pressure and East Side Subareas that would in turn help to control seawater intrusion.

1999 - Salinas River Watershed Management Action Plan, Central Coast Regional Water Quality Control Board
Miscellaneous Monterey and San Luis Obispo County Documents and Reports
To more effectively protect and improve water resources, the Action Plan attempts to develop local solutions to local problems. Many significant identified water quality impacts in the Salinas River Watershed, such as erosion and sedimentation, nitrates in the groundwater and surface water, and older, discontinued pesticides in sediments and animal tissues, are primarily associated with nonpoint pollution sources. Also, widespread groundwater pumping contributes significantly to seawater intrusion into the coastal aquifers. The Action Plan approach includes: 1. devoting additional Regional Board resources to watershed activities, 2. increasing the Regional Board presence by developing partnerships with landowners, local governments, resource agencies …
1999 - Water Resources And Land Use Change In Salinas Valley, Watershed Institute Report No. Wi-1999-01
Miscellaneous Monterey and San Luis Obispo County Documents and Reports
The 1999 report prepared by Fred Watson, Lars Pierce, Mel Mulitsch, Wendi Newman, Adrian Rocha, Mark Fain and Jodiah Nelson of the Watershed Institute, describes the progress made toward the use of computer modeling to provide both understanding and predictive capability. The Salinas River watershed of over 11,000 square kilometers supports large areas of intensive agriculture production, including large areas of intensive crop production, and extensive cattle ranches supporting annual grasslands. Mainly a dry climate with limited surface water resources, the valley has a finite groundwater system. Agriculture accounts for 93.5% of the groundwater extractions that exceed recharge by 40,000-50,000 …
2015, Aug. 20 - Groundwater Recharge On East Side Soils Of The Salinas Valley
2015, Aug. 20 - Groundwater Recharge On East Side Soils Of The Salinas Valley
Miscellaneous Monterey and San Luis Obispo County Documents and Reports
Discussion of the historically low groundwater levels in the Salinas Valley, noting that the shallower wells have become unreliable. As the groundwater levels drop below sea level, the seawater intrusion in the coastal aquifers will worsen. Because of the fast-declining groundwater levels on the east side of the Salinas Valley, the potential for seawater moving inland increases. Enhancing recharge in these areas would be beneficial in reducing seawater intrusion while lowering flood risk and erosion damage. The article reviews potential strategies to increase infiltration of rainwater during winter storms thereby recharging the underlying aquifer.
2017 - Land Use Trends Salinas River Watershed And Groundwater Basin 1771-2015 [Draft] By Dr. Peter Reinelt
Related Research and Documents
Data collated from multiple sources from 1771 through 2015 is used to estimate agricultural land use in the Salinas River Watershed and Groundwater Basin. Institutional responsibility for collecting and maintaining data changed with evolving sovereignty over the region and later with state and county organizational changes. As institutional focus evolved, the type and form of data collected also changed. Therefore, the compiled data often used different units of measurements and have various levels of completeness. Thus, procedures are developed here to collate the data into a consistent form by transforming all cropping data sets to a per acre basis and …
