Digital-model simulation of the glacial-outwash aquifer, Otter Creek-Dry Creek basin, Cortland County, New York
O. J. Cosner, J. F. Harsh
1978, Water-Resources Investigations Report 78-71
The city of Cortland, New York, and surrounding areas obtain water from the highly productive glacial-outwash aquifer underlying the Otter Creek-Dry Creek basin. Pumpage from the aquifer in 1976 was approximately 6.3 million gallons per day and is expected to increase as a result of population growth and urbanization. A...

Results and interpretation of geophysical studies near the Picacho Fault, south-central Arizona
Leroy W. Pankratz, Hans D. Ackermann, Robert C. Jachens
1978, Open-File Report 78-1106
Earth fissuring attributed to ground-water withdrawal occurs throughout south-central Arizona. A large zone of active fissures is located near Picacho, Arizona on the eastern rim of a large subsidence bowl. The main fissure has been named the Picacho fault. During February and March 1977, approximately 6.5 km of seismic-refraction lines...
Ages of flow units in the far eastern lunar maria based on crater density
Joseph M. Boyce
1978, Open-File Report 78-879
The distribution of major geologic units of uniform relative age exposed in the far eastern maria (i.e., Mare Marginis, Mare Smythii, and Mare Crisium) and Mare Humorum was compiled in map form on the basis of a crater density mapping technique. Correlation of crater densities and radiometric ages of Apollo...
Quantitative hydrogeology of the Upper Republican Natural Resources District, southwest Nebraska
Eric G. Lappala
1978, Water-Resources Investigations Report 78-38
Ground-water use for irrigation from the Ogallala Formation }'as in-creased rapidly in the Upper Republican Natural Resources District in southwest Nebraska. Water levels declined as much as 16 feet between 1952 and 1975. Discharge of the aquifer to streams was reduced by as much as 19 percent between 1967 and...
Water-resources appraisal of the Wet Mountain Valley, in parts of Custer and Fremont counties, Colorado
C.J. Londquist, R.K. Livingston
1978, Water-Resources Investigations Report 78-1
The Wet Mountain Valley is an intermontane trough filled to a depth of at least 6,700 feet with unconsolidated deposits. Ground water occurs under both artesian and water-table conditions within the basin-fill aquifer and ground-water moverment is toward Grape and Texas Creeks. The depth to the water table is less...
Physiography and surficial geology of the copper-nickel study region, northeastern Minnesota
P. G. Olcott, D. I. Siegel
1978, Water-Resources Investigations Report 78-51
The Copper-Nickel study region lies in the Superior Upland physiographic province and is located approximately 60 miles north of Duluth and 100 miles southeast of International Falls, Minnesota. It straddles the Laurentian Divide, which separates Hudson Bay and Lake Superior drainage. The topography exhibits a southwesterly trending lineation that parallels...
A guide to obtaining information from the USGS 1978
Paul F. Clarke (compiler), Helen E. Hodgson, Gary W. North
1978, Circular 777
For almost 100 years, the USGS (U.S. Geological Survey) has served Federal, State, and local governments and the public by collecting, analyzing, and publishing detailed information about the Nation 's mineral, land, and water resources. This information is released in a variety of map, book, and other formats and is...

Nitrogen, phosphorus, organic carbon, and biochemical oxygen demand: in Florida surface waters, 1972
Matthew I. Kaufman, J.E. Dysart
1978, Water-Resources Investigations Report 78-43
Water samples were collected during spring and autumn 1972 from about 100 surface-water sites in Florida. The samples were analyzed for the plant nutrients, nitrogen and phosphorus. In most waters, nitrogen concentrations are less than 2.0 milligrams per liter as nitrogen, and organic nitrogen is dominant. Median total nitrogen concentration...
Monthly fluctuations in the quality of ground water near the water table in Nassau and Suffolk Counties, Long Island, New York
Brian G. Katz, Stephen E. Ragone, Juli B. Lindner-Lunsford
1978, Water-Resources Investigations Report 78-41
Water samples from wells in a sewered and an unsewered suburban area and an unsewered rural area on Long Island, N.Y. were collected and analyzed monthly from August 1975 to July 1976 to determine the concentrations of chloride, sulfate, and nitrate in ground water near the water table. Short-term and...
Computer modeling of ground-water availability in the Pootatuck River Valley, Newtown, Connecticut
F.P. Haeni, Elinor H. Handman
1978, Water-Resources Investigations Report 78-77
A hydrologic analysis of the stratified drift in Newtown, Conn., based on available data, test drilling, seismic refraction profiling, and the stream-aquifer connection was performed using a digital computer model. Simulated pumping indicates that a total of 4.0 million gallons of water per day (Mgal/d) can be withdrawn from the...

Dissolved-solids budget of Lake Okeechobee, Florida, October 1964 to September 1974
David V. Maddy
1978, Water-Resources Investigations Report 77-97
Lake Okeechobee is a major surface-water storage facility for south Florida. A dissolved-solids budget for Lake Okeechobee was computed for Oct. 1964 to Sept. 1974, a 10-year budget period. Calculations were based on records of daily discharge, daily specific conductance measurements, and regression equations relating dissolved-solids concentrations and specific conductance....

1978, Open-File Report 79-261
Eagle Valley is a topographic and ground-water basin in the west-central area of Nevada. The demand for water in the valley is approaching the limits of the locally available resource, which is the water yield of 9,000 acre-feet per year from the adjacent mountain areas.The steady-state pumping rate from the...

Unsteady solute-transport simulation in streamflow using a finite-difference model
Larry F. Land
1978, Water-Resources Investigations Report 78-18
This report documents a rather simple, general purpose, one-dimensional, one-parameter, mass-transport model for field use. The model assumes a well-mixed conservative solute that may be coming from an unsteady source and is moving in unsteady streamflow. The quantity of solute being transported is in the units of concentration. Results are...

A rainfall-runoff modeling procedure for improving estimates of T-year (annual) floods for small drainage basins
Robert W. Lichty, Fred Liscum
1978, Water-Resources Investigations Report 78-7
Maps depicting the influence of a climatic factor, C, on the magnitude of synthetic T-year (annual) floods were prepared for a large portion of the eastern United States. The climatic factors were developed by regression analysis of flood data using a parametric rainfall-runoff model and long-term rainfall records. Map estimates...
