2018 - Groundwater Management In California, Michael Hanemann
Related Research and Documents
In 2014, the California legislature for the first time took some steps to create a framework for regulating groundwater pumping in over-drafted basins by adopting the Sustainable Groundwater Management Act (SGMA), representing California's first statewide groundwater management planning program. SGMA called for local agencies to develop groundwater sustainability plans within the next five to seven years and then achieve sustainable levels of groundwater extraction by approximately 2040 to 2045. California's prior efforts to regulate groundwater extraction is discussed, as well as groundwater depletion.

1998 - 2030 Land Use And Water Needs Conditions
Miscellaneous Monterey and San Luis Obispo County Documents and Reports
Documentation of the methodology and data used to estimate the land use, M&I water needs, and pumped agricultural water under the 2030 conditions. One of the primary goals of the Salinas River Basin Management Plan (BMP) is to meet the agricultural, and municipal and industrial water needs of the Valley under the existing conditions (1995 level of development) as well as, under the future conditions (2030 level of development), while stopping the seawater intrusion and balancing the hydrologic conditions in the basin. In order to meet the 2030 water needs, a reasonable estimate of land use and water use conditions …

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.

Multi-Element Fingerprinting Of Waters To Evaluate Connectivity Among Depressional Wetlands, Yuxiang Yuan, Xiaoyan Zhu, David M. Mushet, Marinus L. Otte

Establishing the connectivity among depressional wetlands is important for their proper management, conservation and restoration. In this study, the concentrations of 38 elements in surface water and porewater of depressional wetlands were investigated to determine chemical and hydrological connectivity of three hydrological types: recharge, flow-through, and discharge, in the Prairie Pothole Region of North America. Most element concentrations of porewater varied significantly by wetland hydrologic type (p < 0.05), and increased along a recharge to discharge hydrologic gradient. Significant spatial variation of element concentrations in surface water was observed in discharge wetlands. Generally, higher element concentrations occurred in natural wetlands compared to wetlands with known disturbances (previous drainage and grazing). Electrical conductivity explained 42.3% and 30.5% of the variation of all element concentrations in porewater and surface water. Non-metric multidimensional scaling analysis showed that the similarity decreased from recharge to flowthrough to discharge wetland in each sampling site. Cluster analysis confirmed that element compositions in porewater of interconnected wetlands were more similar to each other than to those of wetlands located farther away. Porewater and surface water in a restored wetland showed similar multi-element characteristics to natural wetlands. In contrast, depressional wetlands connected by seeps along a deactivated drain-tile path and a grazed wetland showed distinctly different multi-element characteristics compared to other wetlands sampled. Our findings confirm that the multi-element fingerprinting method can be useful for assessing hydro-chemical connectivity across the landscape, and indicate that element concentrations are not only affected by land use, but also by hydrological characteristics.

1994 - Managing Water For Drought, U.S. Army Corps Of Engineers And Institute For Water Resources
Miscellaneous Federal Documents & Reports
The purpose of the report was to explain the procedure for cooperative federal-state drought preparedness studies, to indicate how the studies related to the longstanding principles and guidance for federal water resources investigations, and to indicate the means of implementing conclusions arrived at in any given region. This 1994 report, developed during a four-year National Study of Water Management, summarizes the method of improving water management during drought. The method was tested and refined in four field studies in different parts of the country, in which teams of water managers and users worked together to reduce drought impacts. In each …
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 …

Monterey County Water Resources Agency Water Reports
In order to fulfill Monterey County's need for a long-term water resources management plan to ensure good quality water, improve existing water quality, and to provide adequate water supplies, the county developed the Salinas River Basin Management Plan. The goal was to stop seawater intrusion, create a long-term balance between recharge and withdrawal, and to provide a sufficient water supply for Salinas Valley up to the year 2030. Due to complexities of the hydrologic process and their interaction on a basin-wide scale, sophisticated analytical methods and tools are used for better understand the nature and behavior of the hydrologic system, …
