Excerpt: The purpose of this report is to provide the Farm Security Administration guidance in developing, under the provisions of the Water Facilities Act, ground water for irrigation of lands in the North Central Valley. The scope of the report is limited to a description and an analysis of the physical conditions of the Valley as they pertain to ground-water development. The discussion of the agricultural, geological and ground-water conditions of the North Central Valley is stated in general terms with more detailed information of local features being presented in the analysis of conditions in the specific water-supply areas or subareas which combine to make up the total area covered in this report. Some areas have been discussed only generally and some not at all, whereas others have been dealt with in greater detail; the reason for this approach is that, although ground water is present throughout the Valley, the demands for its development by Farm Security Administration clients as a supply of irrigation water are restricted at this time to only a few localities. In other words, areas where an interest in using ground water for irrigation has been evidenced by requests for assistance in drilling wells have been treated in more detail.
