Abstract: Ground water continues to discharge into the Navidad and Lavaca Rivers by seepage out-flow even though large amounts of ground water are pumped for irrigation. Although a reduction in streamflow probably has occurred, a complete loss of the low flow of the streams by infiltration to a lowered water table seems remote. The large ground-water withdrawals will continue to cause land-surface subsidence, which will range from 0.012 foot to more than 0.026 foot per year. A minimum of about 0.013 to 0.015 foot of annual subsidence at the upper ends of the proposed reservoir and a maximum of about 0.019 foot near the dam site can be expected. Structural failures of manmade features have not occurred from the subsidence, but regional changes in the land slope have occurred and will continue . Numerous fault traces have been mapped in the area, but most of the faults are inactive. If movement along the fault planes should occur, the vertical displacement probably will not exceed the total subsidence.

The U. S. Atomic Energy Commission conducted an airborne radioactivity survey of the Red River region of Texas and Oklahoma beginning in December 1955 and ending in May 1956. All or parts of Archer, Clay, and Montague Counties in northern Texas and Carter, Cotton, Jefferson, and Stephens Counties in southern Oklahoma were surveyed. Particular attention was paid to those areas where exposures are found of red beds of the Permian Wichita Group. Field examinations were conducted of anomalies discovered by airborne reconnaissance as well as those reported by private individuals. Forty localities were examined, the majority in sandstones, siltstones, or conglomerates. Uranium and copper minerals were identified at several localities. Ferruginous staining, bleaching of the sandstone color, calcium carbonate cement, and carbonized plant remains are common to the deposits

Abstract: Experiments using highly turbid water from playa lakes for injection into the Ogallala Formation have resulted in greatly decreased yield of the recharge wells. Recharge of ground or surface water of good quality has indicated, however, that injection through wells in an effective method of recharging the aquifer. Water that is slightly turbid can be successfully injected for a period of time, but generally results in constantly declining yields and capacity for recharge. Redevelopment through pumping and surging significantly prolongs the life of recharge wells under some conditions. Surface spreading is little practiced on the High Plains, but locally may be a feasible means of artificial recharge.

From abstract: The analyses indicate that in a fully-developed residential area, the flood peaks with be 1.2 to 1.4 times those from an undeveloped area; and the annual direct runoff will be about double that from an undeveloped area. Data were not sufficient to determine the increase in runoff from a highly industrialized area where the effective imperviousness approaches 100 percent.

Abstract: Removal of water, oil, and gas from the subsurface in Harris and Galveston Counties, Texas, has caused a decline in fluid pressures, which in turn has resulted in subsidence of the land surface. Subsidence of the land surface at Seabrook is due principally to the removal of water. Significant subsidence of the land surface probably began after 1920, and a minimum of about 3.3 feet (1.0 m) and a maximum of about 4.3 feet (1.3 m) of subsidence had occurred at Seabrook by 1973. Probable future subsidence was calculated by two different methods for each of two different loading situations. In the first loading situation, case I, the artesian heads in the Alta Lorna Sand (Rose, 1943) and Evangeline aquifer would continue to decline at the respective rates of 8 feet (2.4 m) per year and 7 feet (2.1 m) per year until 1980 and then cease. In the second loading situation, case II, the artesian heads in the Alta Lorna Sand and Evangeline aquifer would continue to decline at rates of 8 and 7 feet (2.4 and 2.1 m) per year until 1990 and then cease.

Abstract: Subsidence in the Baytown area is becoming critical because much of the area is subject to inundation by high tides. Withdrawals of water from industrial wells and declines in artesian pressures began about 1918. As much as 280 feet (85.3 meters) of artesian-head decline has occurred in the Evangeline aquifer, and as much as 320 feet (97.5 meters) of decline has occurred in the Alta Lorna Sand. Subsidence of the land surface began about 1920, and as much as 8.2 feet (2.5 meters) of subsidence had occurred by 1973. Future subsidence was calculated for two loading situations. Case I provided that the artesian heads in the Alta Lorna Sand and Evangeline aquifer would continue to decline at a rate of 6 feet (1.8 meters) per year until 1980. Case II provided that artesian head in the Alta Lorna Sand and Evangeline aquifer would continue to decline at a rate of about 6 feet (1.8 meters) per year until about 1995. The ultimate subsidence expected for the assumed conditions of case I and case II is 11.4 feet (3.47 meters) and 15.1 feet (4.60 meters), respectively.
