Water resources data for Florida. Part 2. Water quality records
Water Resources Division, U.S. Geological Survey
1974, Water Data Report FL-71-2
Water-resources investigations of the U. S. Geological Survey include the collection of water quality data on the chemical and physical characteristics of surface- and ground-water supplies of the Nation. These data for the 1971 water year for the quality of surface waters in Florida are presented in this report. The...
Mineral resources of proposed additions to the Salmon-Trinity Alps Primitive Area, California
Preston E. Hotz, Robert C. Greene, Terry J. Close, Robert K. Evans
1974, Open-File Report 74-71
A mineral survey of four areas totalling 80 square miles, not included during the 1968-70 examination of the proposed Salmon-Trinity Alps Wilderness, was made by the U.S. Geological Survey and U.S. Bureau of Mines in 1973. Geological Survey personnel mapped the geology and collected stream-sediment and rock samples for spectrographic...
Sediment transport by streams draining into the Delaware Estuary
Lawrence J. Mansue, Allen B. Commings
1974, Water Supply Paper 1532-H
The quantity of sediment transported by streams draining into the Delaware estuary from Pennsylvania, New Jersey, and Delaware varies areally according to geology, physiography, and land use. Of the estimated total sediment load of 1.6 million tons entering the Delaware estuary annually, about 48 percent is contributed by the Delaware...
A special planning technique for stream-aquifer systems
C.T. Jenkins, O. James Taylor
1974, Open-File Report 74-242
The potential effects of water-management plans on stream-aquifer systems in several countries have been simulated using electric-analog or digital-computer models. Many of the electric-analog models require large amounts of hardware preparation for each problem to be solved and some become so bulky that they present serious space and access problems....
Water quality of hydrologic bench marks; an indicator of water quality in the natural environment
James E. Biesecker, Donald K. Leifeste
1974, Circular 460-E
Water-quality data, collected at 57 hydrologic bench-mark stations in 37 States, allow the definition of water quality in the 'natural' environment and the comparison of 'natural' water quality with water quality of major streams draining similar water-resources regions. Results indicate that water quality in the 'natural' environment is generally very...
Ground water in the Corvallis-Albany area, central Willamette Valley, Oregon
Frank J. Frank
1974, Water Supply Paper 2032
The Corvallis-Albany area is part of the alluvial plain that lies between the Cascade and Coast Ranges in the central Willamette Valley in northwestern Oregon. As used in this report, the Corvallis-Albany area consists of approximately 210 square miles and includes a part of the lower foothills of the Coast...
Water resources of the Rum River Watershed, east-central Minnesota
Donald W. Ericson, Gerald F. Lindholm, John O. Helgesen
1974, Hydrologic Atlas 509
The Rum River, a tributary of the Mississippi River, drains an elongate area of about 1,550 square miles. The source of the Rum River is Mille Lacs Lake. Much of the northern half of the watershed is forested, and there are large areas of swampland. Population is most concentrated in...
