E. WOOD and G. H. DAVIS ABSTRACT The Avenal-McKittrick area consists of about 850 square miles on the south west side of the San Joaquin Valley, extends southeastward from the towns of Avenal and Kettleman City to the Elk Hills. Except for about 16,000 acres in several isolated localities, the area is uninhabited desert most of the year, al though extensive grazing is carried on during winter and spring. The area includes Kettleman and Antelope Plains, Antelope and McLure (also known as Sunflower) Valleys, and the area south of Tulare Lake. The geologic units of the area are classed as consolidated rocks and uncon- solidated deposits. The first group includes consolidated non-water-bearing rocks and semiconsolidated rocks of Jurassic to Pliocene age which in general contain connate water of poor quality; locally at shallow depth fresh water is present in them. Most of the formations contain fold- and fault-induced frac tures, and these openings probably convey small quantities of water to the adjacent unconsolidated deposits. The second group consists of unconsolidated to loosely consolidated water-bearing deposits of continental origin which sup ply nearly all the water pumped from wells. These deposits include the struc turally deformed Tulare formation of late Pliocene and Pleistocene (?) age and the alluvium of Pleistocene and Recent age, which in most places unconform- ably overlies the Tulare. Both units are composed of generally poorly sorted silty materials containing lenticular bodies of sand and gravel derived from the Coast Ranges and deposited by streams on extensive alluvial fans. The allu vium is only moderately permeable, and, although the water-bearing properties of the Tulare are little known, it probably is also only moderately permeable. Lacustrine and fiood-basin sediments of Pleistocene and Recent age, present in the bed of Tulare Lake and along Buena Vista Slough, consist of nearly fiat- lying well-stratified silt, clay, and fine sand which generally are poorly perme able. The alluvium and the Tulare formation range in thickness from a few feet along the western border of the valley to several thousand feet beneath the valleys and plains. However, because of comparatively late structural deforma tion in the area, the deposits vary considerably in thickness for short dis tances. Over the crests of buried anticlines the deposits thin considerably, and along the flanks and in adjoining synclinal troughs they thicken rapidly. Recharge to the unconfined and semiconfined bodies of ground water may be by seepage loss from streams, by deep penetration of imported water applied for irrigation in excess of plant requirements, by losses of imported water through irrigation canals and ditches, and by deep penetration of rainfall. However, seepage loss from intermittent streams draining the Coast Ranges 2 GROUND-WATER CONDITIONS, AVENAL-McKITTRICK
