Physical and chemical data for northern San Francisco Bay, California, September through November, 1984
Allan Y. Ota, L. E. Schemel, S.W. Hager
1986, Open-File Report 86-228
This report presents physical and chemical data for northern San Francisco Bay waters. Samples were collected during the late summer and fall of 1984 during six cruises at near-two-week intervals. Bay waters were sampled at designated (historical) stations and selected salinitis along the deep channel of northern San Francisco Bay....
Gas-film coefficients for the volatilization of ketones from water
R. E. Rathbun, D. Y. Tai
1986, Water Supply Paper 2286
Volatilization is a significant process in determining the fate of many organic compounds in streams and rivers. Quantifying this process requires knowledge of the mass-transfer coefficient from water, which is a function of the gas-film and liquid-film coefficients. The gas-film coefficient can be determined by measuring the flux for the...
Water resources data, Florida, water year 1985, Volume 1A: Northeast Florida-surface water
Water Resources Division, U.S. Geological Survey
1986, Water Data Report FL-85-1A
Water resources data for the 1985 water year in Florida consist of continuous or daily discharge for 285 streams, periodic discharge for 38 streams, miscellaneous discharge for 110 streams, continuous or daily stage for 124 streams, periodic stage for 32 streams, peak discharge for 98 streams, and peak stage for...
Comparison of flume and towing methods for verifying the calibration of a suspended-sediment sampler
J.P. Beverage, J.C. Futrell
1986, Water-Resources Investigations Report 86-4193
Suspended-sediment samplers must sample isokinetically (at stream velocity) in order to collect representative water samples of rivers. Each sampler solo by the Federal Interagency Sedimentation Project or by the U.S. Geological Survey Hydrologic Instrumentation Facility has been adjusted to sample isokinetically and tested in a flume to verify the calibration....
Hydrogeologic and water-quality characteristics of the Red River-Winnipeg aquifer northwestern Minnesota
J. F. Ruhl, D. G. Adolphson
1986, Water-Resources Investigations Report 84-4111
The Red River-Winnipeg aquifer of Ordovician age occupies a depression in the Proterozoic crystalline bedrock of northwestern Minnesota. The Winnipeg Formation, which underlies the Red River Formation, consists of two units: A lower shaley mudstone and an upper medium-grained sandstone. The Red River Formation consists of a lower dolomitic, dark-gray...
Channel geometry and hydrologic data for six eruption-affected tributaries of the Lewis River, Mount St. Helens, Washington, water years 1983-84
H. A. Martinson, H.E. Hammond, W.W. Mast, P.D. Mango
1986, Open-File Report 85-631
The May 18, 1980, eruption of Mount St. Helens generated a lateral blast, lahars, and tephra deposits that altered stream channels in the Lewis River drainage basin. In order to assess potential flood hazards, monitor channel adjustments, and construct a sediment budget for disturbed drainages on the east and southeast...
Potentiometric-surface map of the Wyodak-Anderson coal bed, Powder River structural basin, Wyoming, 1973-84
Pamela B. Daddow
1986, Water-Resources Investigations Report 85-4305
Previous water level maps of shallow aquifers in the Powder River structural basin in Wyoming were based on water levels from wells completed in different stratigraphic intervals within thick sequences of sedimentary rocks. A potentiometric surface using water levels from a single aquifer had never been mapped throughout the basin....
Quality of water resources of the Ouachita National Forest, Arkansas
Elizabeth F. Cole, E. E. Morris
1986, Water-Resources Investigations Report 86-4166
Surface water and groundwater quality was documented in the Ouachita National Forest by collecting surface water quality data at 15 points and groundwater quality data at 11 sites from April 1984 through August 1985. The data were compared to drinking water standards and the results are tabulated. Surface water in...
Water resources data, Wyoming, water year 1985
S. A. Druse, Samuel J. Rucker IV
1986, Water Data Report WY-85-1
Water resources data for the 1985 water year for Wyoming consists of records of stage, discharge and water quality of streams; stage and contents of lakes and reservoirs; and water levels and water quality of ground water. This report contains discharge records for 187 gaging stations; stage and contents for...
Hydrogeology of the eastern part of the Salt River Valley area, Maricopa and Pinal Counties, Arizona
R. L. Laney, Mary Ellen Hahn
1986, Water-Resources Investigations Report 86-4147
The Salt River Valley is a major agricultural and metropolitan area in semiarid south-central Arizona. Groundwater in the permeable sedimentary deposits underlying the area is a major water supply for agricultural, municipal, and industrial users. Groundwater levels have declined as much as 400 ft in recent years. Management of the...
Potentiometric surface, ground-water withdrawals, and recharge area for the Lisbon aquifer in Alabama, fall 1982
John S. Williams, Michael Planert, Sydney S. DeJarnette
1986, Water-Resources Investigations Report 86-4120
The U.S. Geological Survey began a nationwide program in 1978, termed Regional Aquifer-System Analysis (RASA), to study a number of the major aquifer systems that provide a significant part of the country 's water supply. One of the aquifer systems chosen for study was the thick and extensive sequence of...
Climatic data for the Cottonwood Lake area, Stutsman County, North Dakota 1982
A.M. Sturrock, B.A. Hanson, J.L. Scarborough, T. C. Winter
1986, Open-File Report 86-477
Research on the hydrology of the Cottonwood Lake area, Stutsman County, North Dakota, includes study of evaporation. Presented here are those climatic data needed for energy-budget and mass-transfer evaporation studies, including: water-surface temperature, sediment temperature dry-bulb and wet-bulb air temperatures, vapor pressure at and above the water surface, wind speed,...

Simulation analysis of water-level changes in the Navajo sandstone due to changes in the altitude of Lake Powell near Wahweap Bay, Utah and Arizona
B. E. Thomas
1986, Water-Resources Investigations Report 85-4207
A two-dimensional, finite difference, digital computer model was used to simulate various concepts of groundwater flow near Wahweap Bay, Lake Powell. The filling of Lake Powell started in March 1963; and by 1983 the lake had risen almost 550 ft. This resulted in a maximum observed water level rise of...
Ground-water quality in Nevada -- A proposed monitoring program
Jon O. Nowlin
1986, Open-File Report 78-768
A program was designed for the systematic monitoring of ground-water quality in Nevada. Basic hydrologic and water-quality principles are discussed in the formulation of a rational approach to developing a statewide monitoring program. A review of ground-water monitoring efforts in Nevada through 1977 indicates that few requirements for an effective...
