Excerpt from Water Supply Conditions in Southern California During 1955 and 1956 The Legislature, by Chapter 832, Statutes of 1929, directed that exploration and investigation be conducted for the furtherance of a coordinated plan for the conservation, development and utilization of the water resources of California. As a result of this legislation, the Division of Water Resources undertook a continuing hydrologic investigation of the southern California area. Effective July 5, 1956, the responsibilities of the Division of Water Resources, Department of Public Works, were assigned to the Department of Water Resourcespursuant to Chapter 52, Statutes of 1956. As a part of the investigation, Bulletin No. 39 was published in 1932, containing Records of Ground water Levels at Wells. Since 1932, water levels at selected wells have been published annually in Bulletins Nos. 39-a through 394w, which was the last of the lettered series reports. This report, Bulletin No. Is the first of the numbered series reports and follows Bulletin No. B96w with no interruption in the continuity of data. The locations and descriptions of the wells referred to in the earlier bulletins were published in Bulletin No. 39, and are shown on Maps 1 through 8, accompanying that bulletin. The locations and descriptions of wells in the San Jacinto and Antelope Valleys were first published in Bulletin No. 39=j, and are shown on Maps 9 through 11 included in that bulletin. Seasonal precipitation data from United States Weather Bureau records, as well as from records at stations not included in official publica tions of that agency, were first published in Bulletin No. 39-a and have been incorporated in all subsequent publications of the series. Monthly records from a few key United States Weather Bureau stations were first published in Bulletin No. 39 d. A.map showing the location of precipitation stations for which seasonal records are published was included in Bulletin No. 39-a.
