Operating manual for the miniservo-control tester
W.L. Rapp
1986, Open-File Report 85-690
Ever since the implementation of servo-control units (regular and minimodels) with manometers at U. S. Geological Survey streamflow stations, the need for an effective and efficient servo-control unit tester has been paramount among field personnel. In numerous cases, servo-control unit failures were blamed on battery failures and vice versa. There...
Activities of the U.S. Geological Survey Water-Resources Division in North Carolina, 1986
J. F. Turner (compiler), R.J. Deckard
1986, Open-File Report 86-226
Water resources programs conducted by the U.S. Geological Survey in the state of North Carolina during 1985 and proposed programs for 1986 are described. This is the first in a series of biennial progress reports on Survey activities in the state. Activities such as gathering, interpreting and publishing hydrologic data...
Preliminary results of organic geochemical and stable isotope analyses of Newark supergroup rocks in the Hartford and Newark basins, Eastern U.S.
L.M. Pratt, A.K. Vuletich, C.A. Shaw
1986, Open-File Report 86-284
Preliminary stage-discharge relations (limit curves) have been defined for Aliceville Lock and Dam covering the period February 1980 to May 1983 (Nelson and Ming, 1983). Subsequent data collected at the dam indicates a need for a revision to the preliminary curves. Due to channel instability in the vicinity, periodic review...
Hydrologic data from Roan Creek and Parachute Creek basins, northwestern Colorado
D. B. Adams, K.E. Goddard, R.O. Patt, K.C. Galyean
1986, Open-File Report 83-859
Hydrologic data obtained from a comprehensive study of the Roan Creek and Parachute Creek basins are presented in this report. The purpose of this study was to inventory and appraise the predevelopment hydrologic conditions in these basins. The study was conducted from October 1975 through September 1981 and was one...
Methods for estimating magnitude and frequency of floods in Montana based on data through 1983
R. J. Omang, Charles Parrett, J. A. Hull
1986, Water-Resources Investigations Report 86-4027
Equations are presented for estimating flood magnitudes for ungaged sites in Montana based on data through 1983. The State was divided into eight regions based on hydrologic conditions, and separate multiple-regression equations were developed for each region. These equations relate annual flood magnitudes and frequencies to basin characteristics and are...
Ground-water availability in the Black River Basin, New York
Roger Milton Waller
1986, Water-Resources Investigations Report 86-4040
There are three maps in this set, which were prepared in 1966-68 as part of a study on the water resources of the Black River basin in cooperation with the New York State Department of Environmental Conservation. The data presented on the maps show well locations, well yield from bedrock...
Cost effectiveness of the US Geological Survey's stream-gaging program in New York
S.W. Wolcott, W.B. Gannon, W. H. Johnston
1986, Water-Resources Investigations Report 85-4328
The U.S. Geological Survey conducted a 5-year nationwide analysis to define and document the most cost effective means of obtaining streamflow data. This report describes the stream gaging network in New York and documents the cost effectiveness of its operation; it also identifies data uses and funding sources for the...
Hydrologic and climatologic factors affecting water levels of Devils Lake, North Dakota
Gregg J. Wiche
1986, Water-Resources Investigations Report 86-4320
High water levels of Devils Lake, North Dakota, and other terminal lakes, have, in recent years, threatened highways, agricultural land, recreational cabins, and communities located near these lakes. This study was undertaken to describe the hydrology of the Devils Lake basin and to determine how to estimate future water level...
