Evaluation of p,p'-DDT as a reference toxicant in bioassays
Leif L. Marking
1966, Investigations in Fish Control 10
p,p'-DDT was tested as a reference standard toxicant against 19 species of freshwater fish, including 39 lots from 10 sources. In particular, the rapidity, nonselectivity, and consistency of its toxicity to fish were evaluated in 96-hour static bioassays. The chemical was rapidly and consistently toxic to lake trout, carp, green...
Little Sioux River Basin floods
Harlan H. Schwob
1966, Open-File Report 67-196
Highway engineers and many others use flood stages and discharges in the design of bridges and other structures or operations on the flood plain of a stream. These data are provided in the form of gaging-station and other flood records and as flood profiles. Flood-frequency data are used to compute...
Ground water in the San Joaquin Valley, California
Fred Kunkel, Walter Hofman
1966, Open-File Report 66-75
Ladies and gentlemen, it is a pleasure to be invited to attend this Irrigation Institute conference and to describe the Geological Survey's program of ground-water studies in the San Joaquin Valley. The U.S. Geological Survey has been making water-resources studies in cooperation with the State of California and other agencies...
Appraisal of near-surface subsidence on the Panoche Creek fan, Fresno County, California
William B. Bull
1966, Open-File Report 66-13
Near-surface subsidence results chiefly from the compaction of deposits by an overburden load as the clay bond supporting the deposits is weakened by water percolating through the deposits for the first time since burial. About 100 square miles of alluvial-fan deposits in western Fresno County, California, have been affected by...
Water-surface profiles of Raccoon River at Des Moines, Iowa
Philip J. Carpenter, David H. Appel
1966, Open-File Report 67-37
This investigation was undertaken as a part of the cooperative program with the Iowa Institute of Hydraulic Research, the City of Des Moines, and the U.S. Geological Survey.  The purpose of this report is twofold: 1.  To present water-surface profiles and rating curves for existing channel conditions in the 4-mile reach...

E. R. Hedman, E.G. Pearson
1966, Open-File Report 66-61
Severe flooding occurred in southern California in late November and late December 1965 as a result of three heavy storms. Rain occurred on most days during the period November 13-26 and December 28-31, with major amounts distributed in three periods: November 13-19, 21-26, and December 28-31. More than 12 inches...
Salt-water encroachment in southern Nassau and southeastern Queens Counties, Long Island, New York
N.J. Lusczynski, Wolfgang V. Swarzenski
1966, Water Supply Paper 1613-F
Test drilling, extraction of water from cores, electric logging, water sampling, and water-level measurements from 1958 to 1961 provided a suitable basis for a substantial refinement in the definition of the positions, chloride concentrations, and rates of movement of salty water in the intermediate and deep deposits of southern Nassau...
