Water-Bearing Formations <br /> The Mehrten Formation is the oldest of the water-bearing <br /> formations and its upper surface is at an approximate depth of <br /> 800 to 1 ,000 feet beneath the surface. It is probably semi- <br /> confined, and is relatively permeable and commonly yields 1,000 <br /> gallons per minute from wells. The overlying Laguna Formation <br /> has a moderate yield produced from an unconfined to semi- <br /> confined system. 1 ,500 gallons per minute. The highest figure <br /> yield reported for this formation. However , 900 gallons per <br /> minute is the overall average. The upper surface of the Laguna <br /> Formations is at an approximate depth of 125 feet beneath the <br /> surface; however, it is much shallower to the east and deeper to <br /> the west. Above the Laguna Formation lies the Victor formation <br /> which is of no great thickness and most wells penetrate it to <br /> reach deeper strata. Small domestic wells that penetrate into <br /> the Victor indicate it has a yield of approximately 650 gallons <br /> per minute. Above and interbedded with the Victor formation are <br /> alluvial fan deposits and stream channel deposits. The general <br /> uses of water from these formations is for domestic, industrial, <br /> and agricultural applications. <br /> a <br />
