Reconnaissance of the effect of landfill leachate on the water quality of Marshall Brook, Southwest Harbor, Hancock County, Maine
Bruce P. Hansen
1980, Open-File Report 80-1120
A small stream (2.2 square miles drainage area) receiving leachate from a landfill was studied from August through November 1979 to determine the impact of the leachate on water quality. The presence of un-ionized ammonia, considered toxic to some aquatic vertebrates, was indicated in samples taken from sections of the...
Digital-computer model of ground-water flow in Tooele Valley, Utah
Allan C. Razem, Scott D. Bartholoma
1980, Open-File Report 80-446
A two-dimensional, finite-difference digital-computer model was used to simulate the ground-water flow in the principal artesian aquifer in Tooele Valley, Utah. The parameters used in the model were obtained through field measurements and tests, from historical records, and by trial-and-error adjustments. The model was calibrated against observed water-level changes that...
Land-surface subsidence in the Texas coastal region
Karl W. Ratzlaff
1980, Open-File Report 80-969
Land-surface subsidence has been mapped in the Houston-Galveston area and is known to have occurred in other areas within the Texas coastal region. Most of the subsidence has been caused by both the withdrawal of ground water and by the production of oil, gas, and associated ground water. Land-surface subsidence was...
Distribution of aquifers, liquid-waste impoundments, and municipal water-supply sources, Massachusetts
David F. Delaney, Anthony Maevsky
1980, Open-File Report 80-431
Impoundments of liquid waste are potential sources of ground-water contamination in Massachusetts. The map report, at a scale of 1 inch equals 4 miles, shows the idstribution of aquifers and the locations of municipal water-supply sources and known liquid-waste impoundments. Ground water, an important source of municipal water supply, is...
Hydrogeologic data for the Mississippi Embayment of southeastern Missouri
Richard R. Luckey, Dale L. Fuller
1980, Open-File Report 79-421
The Mississippi embayment of southeastern Missouri is a 4 ,000-square-mile agricultural area that is presently (1979) undergoing rapid development for irrigation. In July 1974, a project was initiated to evaluate the water resources of the area, determine the extent of irrigation, and to assess the future potential for irrigation supplies....
Food of alewives, yellow perch, spottail shiners, trout-perch, and slimy and fourhorn sculpins in southeastern Lake Michigan
LaRue Wells
1980, Technical Paper 98
Stomachs of 1,064 alewives (Alosa pseudoharengus), 1,103 yellow perch (Perca flavescens), 246 spottail shiners (Notropis hudsonius), 288 trout-perch (Percopsis omiscomaycus), 454 slimy sculpins (Cottus cognatus), and 562 fourhorn sculpins (Myoxocephalus quadricornis) from Lake Michigan were examined for food contents. Fish were sampled primarily from March to November and nearly all...
Hydrologic analysis of the proposed Badger-Beaver Creeks artificial-recharge project: Morgan County, Colorado
Alan W. Burns
1980, Water-Resources Investigations Report 80-46
A hydrologic analysis of the proposed Badger-Beaver Creeks artificial-recharge project in Morgan County, Colo., was made with the aid of three digital computer models: A canal-distribution model, a ground-water flow model, and a stream-aquifer model. Statistical summaries of probable diversions from the South Platte River based on a 27-year period...
Quality of water and time of travel in Yockanookany River, Choctaw County, Mississippi
Gene A. Bednar
1980, Open-File Report 80-770
An intensive study of a 3.3-mile reach of the Yockanookany River, including a major tributary, was conducted August 29-31, 1978. The quality-of-water data were collected during a period of generally law streamflow and seasonally high air temperatures. These data show that the quality of water in Yockanookany River was generally...
Hurricane Frederic tidal floods of September 12-13, 1979, along the Gulf Coast, Coden-Bellefontaine quadrangles, Alabama
Larry R. Bohman, John C. Scott
1980, Hydrologic Atlas 626
Floodmark elevations and approximate areas flooded by Hurricane Frederic tides of September 12-13, 1979, along coastal areas of Mobile Bay between Bellefontaine and Point Judith, Alabama, are shown on a topographic map. Storm-tide frequency and records of annual maximum tides at Mobile, Alabama, since 1772, are presented. Offshore winds reached...
Waterfowl status report, 1976
1980, Special Scientific Report - Wildlife 227
This report contains information from the 1975-76 midwinter waterfowl survey, the 1976 waterfowl breeding population and production surveys, and the waterfowl harvest surveys for the 1975-76 hunting season. This information was provided by the U.S. Fish and Wildlife Service, the Canadian Wildlife Service, and various cooperating State wildlife conservation agencies....
Hydrologic data for Okaloosa, Walton, and southeastern Santa Rosa counties, Florida
Jeffrey R. Wagner, L. R. Hayes, C.E. Lewis, D. E. Barr
1980, Open-File Report 80-741
This report presents hydrologic and water-quality data collected within Okaloosa, Walton, and southeastern Santa Rosa Counties in northwest Florida. The data are presented in graphs and tables. Groundwater data include descriptions of wells and test holes, analyses of water quality, water level measurements, hydrographs of water levels and chloride concentrations...
Selected hydrologic data from the vicinity of Rayburns and Vacherie salt domes, northern Louisiana salt-dome basin
G.N. Ryals, R. L. Hosman
1980, Open-File Report 80-217
The U.S. Department of Energy is considering salt domes in northern Louisiana as possible sites for storage of nuclear waste from commercial sources. As part of this National Waste Terminal Storage (NWTS) Program, the U.S. Geological Survey is conducting a regional study of the geohydrology of the northern Louisiana salt-dome...
The surficial aquifer at the U.S. Naval Station near Mayport, Florida
Bernard J. Franks
1980, Open-File Report 80-765
The surficial aquifer at the U.S. Naval Station near Mayport, Florida, consists of about 70 feet of unconsolidated sand, shell , and clay. The principal water-bearing zone is a shell bed 35 to 55 feet below land surface. The aquifer is unconfined, and the water table was about 4 feet...

Probable high ground-water levels on Cape Cod, Massachusetts
Michael H. Frimpter
1980, Open-File Report 80-1008
Water-level records from 146 short-term (1 year) observation wells and 13 long-term (16-28 years) observation wells were used to estimate the probable high ground-water level that could occur at any site on Cape Cod. The estimation was based on correlation of a single water-level measurement from a test site with...
