1923 - Irrigation Requirements Of California Lands, Bulletin No. 6, Appendix B, Report To The Legislature

Miscellaneous Documents and Reports

The legislature of 1921 appropriated $200,000 for an investigation of California's water resources by the State Department of Public Works, Division of Engineering and Irrigation. Accordingly, an engineering investigation was completed.

California's agricultural lands are those portions of the state that have suitable soils, disposed in appreciable areas of regular surface conformation, favorable climate, and other requisite conditions for the production of harvestable crops. Included in these, are lands at present deficient in natural moisture, but more or less conveniently situated for the ultimate acquisition of an accessory water supply. These agricultural lands produced, or were capable of producing, the …

2003 - Geohydrologic Framework Of Recharge And Seawater Intrusion In The Pajaro Valley, Santa Cruz And Monterey Counties, California

Miscellaneous Monterey and San Luis Obispo County Documents and Reports

The Pajaro Valley Water Management Agency (PVWMA) must deal with issues of both water supply and water quality. Managing water resources for agricultural and municipal users requires maintaining a reliable water supply to meet growing demands while preventing ground-water overdraft and the related degradation of water quality. Important regional water-quality concerns include increased nitrate concentrations and seawater intrusion. To protect the quantity and quality of the ground-water supplies, the PVWMA has implemented a plan to prevent further seawater intrusion. In order to evaluate how these activities can be conducted most effectively, it is necessary to improve the understanding of the …
