Excerpt from Geology and Ground Waters of the Western Part of San Diego County, California The surface waters, though at times overwhelming in volume, are unfortunately not dependable and require expensive storage and transmission works for their Utilization. There are no perennial streams except at high levels and at a considerable distance from the coast where they are too small to be Of much practical value. Pre cipitation of sufficient magnitude to produce run-off is confined to three or four months of the year, and in years Of average precipitation the larger streams do not maintain a permanent ow for more than five or Six months. TO Obtain from the surface streams the unfailing water supplies required for irrigation and especially for domestic uses, it is necessary to provide large storage reservoirs. Conditions are made even more unfavorable by the wide variations in precipitation from one year to another and by the occasional periods of severe drought. This condition necessitates holding in reserve sufficient water (in storage) to supply the full requirements for a three or four year period. The expense Of providing the necessary storage works is great, and after the water has been stored the losses by evaporation from the exposed water surface may amount to a large proportion Of the volume originally stored. The problem Of keeping water up to a standard Of potability for domestic use after being held in storage for two or three years is also very difficult.
