A study of the hydrogeology of deep sedimentary basins using the Neogene deposits of the northern Gulf of Mexico basin as a model was initiated by the U.S. Geological Survey in the 1960's (Jones, 1969). This study led to investigations of geopressured-geothermal resources in this basin (Papadopulos and others, 1975;...

In 1978, the U.S. Geological Survey initiated a 5-year study of the High Plains regional aquifer to provide: (1) Hydrologic information needed to evaluate the effects of continued ground-water development; and (2) computer models to predict aquifer response to changes in ground-water development. The plan of study for the High...

Effective improvement of economic and social conditions of Indians living on the Standing Rock Indian Reservation has been hampered by lack of adequate and reliable information about the quantity and quality of water supplies available for development.  Compounding the problem is the recent filling of Oahe Reservoir (now Lake Oahe),...

The general quality of the ground water in the Sacramento Valley , Calif., in terms of dissolved-solids concentration is considered good for irrigation, domestic, and most other uses. This map shows the distribution of dissolved-solids concentrations and is based on about 1,330 chemical analyses collected from about 900 wells between...

Hydrologic data pertaining to the magnitude and areal extent of flooding that occurred on May 24-25, 1981, along Shoal, Walnut, and Little Walnut Creeks in the Austin, Texas, metropolitan area are presented in this atlas.  The flood boundary maps and other flood data provide a technical data base for land-use...

The Kickapoo River valley in southwestern Wisconsin had a devastating flood ($10 million estimated damages) during July 1-5, 1978. The flash flooding was caused by intense storms on June 30 through July 2. Total rainfall accumulation ranged from 5.8 inches near Ontario to 9.5 inches at La Farge. The resulting...

The Denver ground-water basin underlies a 6,700-square-mile area extending from Greeley in the north to Colorado Springs in the south, and from the Front Range in the west to near Limon in the east.  The four major bedrock aquifers that occur in the basin are the Laramie-Fox Hills aquifer (the...

Shown on the Gulf Breeze-Fort Barrancas topographic map are floodmark elevations and approximate areas flooded by Hurricane Frederic tides of September 12-13, 1979, along the shores of Big Lagoon, Pensacola Bay, Santa Rosa Sound, and the Gulf of Mexico from Seaglades eastward to Pensacola Beach, Florida. The still water elevations...

Shown on a topographic map are floodmark elevations and approximate areas flooded by Hurricane Frederic tides of September 12-13, 1979, along the western shore of Mobile Bay from the southern part of Mobile, Alabama, to the South Fork of Deer River including the inland areas along Deer River and Dog...

Shown on the Oriole Beach-Garcon Point-Holley-South of Holley-Navarre, Fla., topographic map are floodmark elevations and approximate areas flooded by Hurricane Frederic tides of September 12-13, 1979, along the shores of Santa Rosa Sound and the Gulf of Mexico from Pensacola Beach eastward to the Narrows near Fort Walton Beach, Fla....

Shown on a topographic map are floodmark elevations and approximate areas flooded by Hurricane Frederic tides of September 12-13, 1979, along the Mobile Causeway (U.S. Highway 90) from the Tensaw River to Spanish Fort, Alabama, and the eastern shore of Mobile Bay in the vicinity of Spanish Fort. Most buildings...

Shown on a topographic map are floodmark elevations and approximate areas flooded by Hurricane Frederic tides of September 12-13, 1979, along the Mobile and Tensaw Rivers in Mobile and Baldwin Counties, Alabama. Most of the inundated areas shown are marshlands or flood plains of small tributary streams. Storm-tides frequency and...
