1913 - Water Resources Of California, Part Iii, Water-Supply Paper 300 Jan 2019

1913 - Water Resources Of California, Part Iii, Water-Supply Paper 300

Miscellaneous Documents and Reports

The water available for irrigation and domestic supply was the chief factor in the development of southern California, which then had a population of more than 1,000,000 people. The many mountain streams of California afforded abundant hydroelectric power, the utilization of which in manufacturing enterprises and in transportation had been made possible by the progress of electric-power transmission during the previous decade.

Information concerning the quantity of water carried by the streams had been and would continue to be an important factor in the development of these resources, for the fundamental importance of stream-flow data was so thoroughly recognized that …


1920 - Irrigation Of Twelve Million Acres In The Valley Of California; Robert Bradford Marshall Jan 2019

1920 - Irrigation Of Twelve Million Acres In The Valley Of California; Robert Bradford Marshall

Miscellaneous Documents and Reports

By 1920, California's potential wealth in land reached into billions of dollars; 12,000,000 acres of available agricultural lands remained practically untouched. Marshall proposed a large plan that would make the Valley of California the world's greatest garden. The engineering plans for such a project must be comprehensive, for their execution must not only assure the complete reclamation of 12,000,000 acres of valley lands but must also effectively and forever control the river floods and insure safe and continuous river navigation throughout the year. The hydro-electric current generated along most of the streams would furnish all the power necessary for construction …

1921 - Petroleum Resources Of California, Bulletin 89 Jan 2019

1921 - Petroleum Resources Of California, Bulletin 89

Miscellaneous Documents and Reports

By 1921, the increasing demand for petroleum and its products, and the inability of production to keep pace with requirements, for several years, resulted in widespread prospecting throughout the world for possible new oil fields. In California, "wild-cat" wells were being drilled in many localities, some of them in places where even a cursory inspection of the geology would tell the futility of looking for oil. This report aimed to furnish information as to the unfavorable as well as the favorable areas of development of additional petroleum resources in California. The purpose of the report was to briefly take stock …


1929 - California Irrigation Districts, Bulletin No. 21 Jan 2019

1929 - California Irrigation Districts, Bulletin No. 21

Miscellaneous Documents and Reports

The investigation is an enlargement of a study outlined February, 1926, by the late state engineer, Wilbur F. McClure, and cooperating agencies. Work on the project was suspended in 1927 but was resumed early in 1928 at the request of the California Economic Research Council, whose committee on irrigation economics prepared the schedule used in the field investigation.

An earlier report on this subject by the same author covered the situation up to 1915, and was published as Bulletin 2 of the State Department of Engineering. This report, together with Bulletin 2, presented the most complete information it had been …

1994 - Agriculture, Water And California's Drought Of 1987-92, Kenneth W. Umbach.Pdf

Miscellaneous Documents and Reports

The purpose of this paper was to summarize the 1987-1992 drought in the context of agriculture and water in California, to examine the types of response that farmers and institutions could and did use, and to draw lessons from that experience. California would be challenged as it grappled with population growth and environmental concerns. In view of the demand on water supplies made by California's agricultural sector (77 to 80 percent of the "developed" water used in the state, it was especially important to review those responses.
