Slides showing aeromagnetic and gravity data for regional mineral exploration in Colorado, New Mexico, and Arizona
Douglas P. Klein
1983, Open-File Report 83-443
Examples of aeromagnetic and gravity data over 1? x 2? areas are presented for regions near the Cripple Creek mining area, Colorado, and the Lordsburg-Tyrone-Silver City mining areas, southern New Mexico and Arizona. These data indicate broad crustal structures and compositional variations that are marked by magnetization and density contrasts....

Acoustic systems for the measurement of streamflow
Antonius Laenen, Winchell Smith
1983, Water Supply Paper 2213
The acoustic velocity meter (AVM), also referred to as an ultrasonic flowmeter, has been an operational tool for the measurement of streamflow since 1965. Very little information is available concerning AVM operation, performance, and limitations. The purpose of this report is to consolidate information in such a manner as to...

1983, Open-File Report 83-938
The locations of 2 National Weather Service stations, 29 observation wells, 4 stream gages, and 12 lake-stage stations are depicted on a 1:63, 360-scale map. The periods of record and station descriptions are listed. Hydrographs depict water-level fluctuations of 12 lakes during the period 1970-1983. ...
Habitat Suitability Index Models: Longnose sucker
Elizabeth A. Edwards
1983, FWS/OBS 82/10.35
A review and synthesis of existing information were used to develop riverine and lacustrine habitat models for Longnose sucker (Catostomus catostomus), a freshwater fish. The models are scaled to produce an index of habitat suitability between 0 (unsuitable habitat) to 1 (optimally suitable habitat) for freshwater areas of the continental...

Hydrogeologic and water-quality characteristics of the Mount Simon-Hinckley aquifer, southeast Minnesota
R. J. Wolf, J. F. Ruhl, D. G. Adolphson
1983, Water-Resources Investigations Report 83-4031
The Mount Simon-Hinckley aquifer in southeast Minnesota consists of a thick sequence of sandstone that generally yields large quantities of good-quality water to wells. The aquifer is most important as a source of water supply in the Twin Cities area, where it supplies approximately 10 percent of the ground water...

Guidelines for use of water-quality monitors
A. Brice Gordon, Max S. Katzenbach
1983, Open-File Report 83-681
This manual contains methods and procedures used by the U.S. Geological Survey (USGS) for collecting specific conductance, dissolved oxygen, water temperature, and pH data for ground water, streams, lakes, reservoirs, and estuaries by means of permanently installed, continuously recording, water quality monitors. The topics discussed include the selection of monitoring...
Hydrologic data from an area southwest of Tallahassee, Florida, where municipal wastewater effluent is applied by spray irrigation
M.C. Yurewicz
1983, Open-File Report 83-769
The effects of spray irrigation using municipal wastewater effluent on a ground-water system (in particular, on the water of the Floridan aquifer) were investigated. The area irrigated was 4 miles southwest of Tallahassee, Florida, on an area covered in part by pine forest and in part by selected grasses and...

Trends and fluctuations in the potentiometric surface of the Floridan aquifer, west-central Florida 1961-80
D. K. Yobbi
1983, Water-Resources Investigations Report 82-4086
Trends and fluctuations of water levels in wells tapping the Floridan aquifer in west-central Florida during 1961-80 are described in this report. Water levels in most of the study area have not changed appreciably, except in parts of Hardee, Hillsborough, Manatee, Polk, and Sarasota Counties. In these areas, ground-water pumpage...
Hydrogeologic and water-quality characteristics of the Upper Carbonate aquifer, Southeast Minnesota
J. F. Ruhl, R. J. Wolf
1983, Water-Resources Investigations Report 84-4150
The Upper Carbonate aquifer is part of a sequence of sedimentary bedrock units deposited in Paleozoic seas that occupied a depression known as the Hollandale embayment. The aquifer is comprised of four formations, which, in ascending order, are the Galena Dolomite, Dubuque Formation, Maquoketa Shale, and Cedar Valley Limestone. Total...
Occurrence, quality, and use of ground water in Orcas, San Juan, Lopez, and Shaw Islands, San Juan County, Washington
K. J. Whiteman, Dee Molenaar, J.M. Jacoby, G.V. Bortleson
1983, Water-Resources Investigations Report 83-4019
Ground water, which supplies most of San Juan County 's water needs, occurs in both bedrock and glacial drift. Water in the bedrock occurs in fractures in the otherwise dense, poorly permeable rock. Deposits of sand and gravel in the glacial drift provide the best yields to wells drilled into...
A two-dimensional, finite-difference model of the high plains aquifer in southern South Dakota
K.E. Kolm, H. L. Case III
1983, Water-Resources Investigations Report 83-4175
The High Plains aquifer is the principal source of water for irrigation, industry, municipalities, and domestic use in south-central South Dakota. The aquifer, composed of upper sandstone units of the Arikaree Formation, and the overlying Ogallala and Sand Hills Formations, was simulated using a two-dimensional, finite-difference computer model. The maximum...
