Water quality and streamflow data for the West Fork Trinity River in Fort Worth, Texas
S. C. McCutcheon
1985, Water-Resources Investigations Report 84-4330
Water-quality data were collected on a 13.6-mile reach of the West Fork Trinity River in Fort Worth, Texas to test a dynamic Lagrangian model. Flow was steady. Loads of dissolved constituents varied with time at the beginning of the study reach and in the reach, primarily because of photosynthesis. River...
Geochemical controls on dissolved sodium in basalt aquifers of the Columbia Plateau, Washington
P.P. Hearn, W.C. Steinkampf, Gilbert C. Bortleson, B. W. Drost
1985, Water-Resources Investigations Report 84-4304
Miocene basaltic aquifers of the Columbia Plateau are the principal source of water for agricultural, domestic, and municipal use in Washington State. Irrigation with groundwaters with relatively high sodium concentrations has been cause for concern in recent years, because of the tendency of such waters to reduce soil permeability. Chemical...
Map showing abundance and distribution of arsenic in oxide residues of stream-sediment samples, Medford 1 degree by 2 degrees Quadrangle, Oregon-California
Charles L. Whittington, Reinhard W. Leinz, David J. Grimes
1985, Miscellaneous Field Studies Map 1383-J
Stream-sediment sampling in the Medford 1o x 2o quadrangle was undertaken to provide to aid in assessment of the mineral resource potential of the quadrangle. This map presents data on the abundance and distribution of copper in the oxide residues (oxalic-acid leachates) of stream sediments and in the minus-0.18-mm sieve fraction...
Low flows and flow duration of Tennessee streams through 1981
R.H. Bingham
1985, Water-Resources Investigations Report 84-4347
Estimates of low-flow characteristics and flow duration for the period of record at continuous-record streamflow gages are essential in hydrologic studies and water-resources management. This report provides estimates of low flow for 1, 3, 7, 14, 30, 60, and 90 consecutive days for recurrence intervals of 2, 5, 10 ,...
Effects of low-level dams on the distribution of sediment, trace metals, and organic substances in the lower Schuylkill River basin, Pennsylvania
Thomas H. Yorke, John K. Stamer, Gary L. Pederson
1985, Water Supply Paper 2256-B
Heavy use of the Schuylkill River for municipal water supplies and a history of accidental spills and discharges of trace metals and organic substances have been a concern of State and local officials for many years. The U.S. Geological Survey, as part of their River Quality Assessment Program, developed a...
Map showing depth to bedrock in the Seattle 30' by 60' Quadrangle, Washington
J. C. Yount, G.R. Dembroff, G.M. Barats
1985, Miscellaneous Field Studies Map 1692
Maps depicting thicknesses of sedimentary units (isopach maps) are standard tools for interpretation of processes and patterns of sedimentation within basins (Potter and Pettijohn, 1977, p. 283-287). Isopach maps showing the thickness of unconsolidated sedimentary deposits overlying bedrock may help locate sources of aggregate and potential ground-water aquifers. These maps...
Petroleum geology and resources of northeastern Mexico
James A. Peterson
1985, Circular 943
Petroleum deposits (primarily gas) in northeastern Mexico occur in two main basins, the Tertiary Burgos basin and the Mesozoic Sabinas basin. About 90 gas fields are present in the Burgos basin, which has undergone active exploration for the past 30-40 years. Production in this basin is from Oligocene and Eocene...
Sources of water and nitrogen to the Widefield Aquifer, southwestern El Paso County, Colorado
Patrick Edelmann, Doug Cain
1985, Water-Resources Investigations Report 85-4162
The Widefield aquifer near Colorado Springs, Colorado, is recharged primarily by Fountain Creek and, to a lesser extent, by infiltration and percolation of water from the land surface and from groundwater inflow. During the past 20 to 30 years, concentrations of nitrate (as nitrogen) in the Widefield aquifer have increased...
Analyses of flood-flow frequency for selected gaging stations in South Dakota
R.D. Benson, E.B. Hoffman, V.J. Wipf
1985, Water-Resources Investigations Report 85-4217
Analyses of flood flow frequency were made for 111 continuous-record gaging stations in South Dakota with 10 or more years of record. The analyses were developed using the log-Pearson Type III procedure recommended by the U.S. Water Resources Council. The procedure characterizes flood occurrence at a single site as a...
Fishery survey and related limnological conditions of Williams Lake, Hubbard County, Minnesota
W.W. Taylor, J. W. LaBaugh, M.H. Freeberg, D.C. Dowling
1985, Water-Resources Investigations Report 84-4145
Bluegill (Lepomis macrochirus), pumpkinseed sunfish (Lepomis gibbosus), largemouth bass (Micropterus salmoides), yellow perch (Perca flavescens) rock bass (Amploplites rupestris), black crappie (Pomozis nigromaculatus), and northern pike (Esox lucius) were found in Williams Lake, Hubbard County, Minnesota, during a fishery survey of the lake in late August 1982. The most abundant...
Development and testing of highway storm-sewer flow measurement and recording system
F. A. Kilpatrick, W.R. Kaehrle, Jack Hardee, E. H. Cordes, M. N. Landers
1985, Water-Resources Investigations Report 85-4111
A comprehensive study and development of measuring instruments and techniques for measuring all components of flow in a storm-sewer drainage system was undertaken by the U.S. Geological Survey under the sponsorship of the Federal Highway Administration. The study involved laboratory and field calibration and testing of measuring flumes, pipe insert...
