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.

A report about six cretaceous rock formations in the western Wyoming thrust belt.

From purpose of the report: The purpose of this report is to present the available information regarding the relation between the rate of ground-water withdrawal and the rate of decline or artesian pressure in a 40-foot "shell" limestone aquifer that was dewatered during construction of Walter F. George Lock and Dam...The report indicates a potential source of a large supply of ground water available for industrial and other uses in an area readily accessible by barge transportation from the Gulf of Mexico to Columbus, Ga.

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.

From preface: This report is concerned in general with the possible effects of the Cross-Florida Barge Canal on the pre-canal hydrologic regime of the area, and in particular with the effect of the canal on the natural levels, movement, and quality of the ground-water.

Abstract: This report contains lists of stations at which the U.S. Geological Survey collects water data either on a continuous basis or at least on a daily basis. The files contain daily values for streamflow, reservoir levels or contents, water temperatures, specific conductance, sediment discharge plus data for several other quality parameters that are measured by means of monitoring equipment or result from analyses of samples collected on a daily basis. The stations are listed according to station number within each State. The report lists the availanle retrieval options, the machine -readable output options, user charges and how to obtain data.
