Book excerpt: Excerpt from Ventura County Investigation, 1933 Data were secured on stream flow at all strategic points, percola tion into underground basins, and rainfall at all locations at which records had been kept. In addition new records were started. Geology of the region was studied with special reference to its relation to water supply. Most of the water supplies of the county are drawn from the recent alluvials of the valleys which were mechanically analyzed to secure estimates of capacity of the underground reservoirs. Quality of water was investigated and all analyses by others available were utilized together with new analyses made during this investigation. Measurements at wells to determine depth to water table were made consistently and all former measurements available were secured. For water supply estimates the entire area Of the county was divided into basins as shown on Plate I, and each basin was studied individually. From recorded stream discharges and rainfall records the dis charge by months for each of the forty years beginning with fall 1892 was reconstructed, percolation was calculated and Operation of underground reservoirs was reconstructed during the forty years on the basis of present draft. The yield of each of the various surface reservoirs studied was estimated and the cost per acre-foot Of yield calculated. A careful crop survey was made for the entire area. Estimates of present draft on the underground reservoirs and of the ultimate area possible to irrigate were made. Available statistics on irrigated areas at various times in the past were secured.
