Data on the distribution and abundance of submersed aquatic vegetation in the tidal Potomac River and transition zone of the Potomac Estuary, Maryland, Virginia, and the District of Columbia, 1983-1984
Virginia Carter, N. B. Rybicki, R. T. Anderson, T. J. Trombley, G.L. Zynjuk
1985, Open-File Report 85-82
Data on the distribution and abundance of submerged aquatic vegetation were collected in the tidal Potomac River and transition zone of the Potomac Estuary during 1983 and 1984. Plant species were identifed on transects. Water-quality characteristics measured include temperature, specific conductance, and Secchi depth. Maps were made of the distribution...
Water resources data, Texas, water year 1984; Volume 2. San Jacinto River basin, Brazos River basin, San Bernard River basin, and intervening coastal basins
H.D. Buckner, E.R. Carrillo, H.J. Davidson
1985, Water Data Report TX-84-2
Surface-water data for the 1984 water year for Texas are presented in three volumes, appropriately identified as to content by river basins. Data in each volume consist of records of stage, discharge, and water quality of streams and canals; and stage, contents, and water quality of lakes and reservoirs. Also...
Ground-water contribution to the salinity of the Upper Colorado River Basin
J. W. Warner, F.J. Heimes, R.F. Middelburg
1985, Water-Resources Investigations Report 84-4198
A study was conducted to estimate the contribution of groundwater and other natural sources to the salinity of streamflow in the Upper Colorado River Basin. Salt-load estimates were derived from a mass balance using measurements of quantity and quality of base streamflow. Groundwater inflow was considered to represent the bulk...
The Salma Caldera complex, northeastern Arabian Shield, Kingdom of Saudi Arabia
K.S. Kellogg
1985, Open-File Report 85-370
The upper Proterozoic Salma caldera is genetically part of an elongate alkali granitic massif, Jabal Salma. Comenditic ash-flow tuffs, the oldest recognized rocks of the caldera complex, were erupted during caldera collapse associated with the rapid evacuation of the upper, mildly peralkaline part of a zoned magma reservoir. Within the...
Occurrence of natural radium-226 radioactivity in ground water of Sarasota County, Florida
R. L. Miller, Horace Sutcliffe
1985, Water-Resources Investigations Report 84-4237
Water that contains radium-226 radioactivity in excess of the 5.0-picocurie-per-liter limit set in the National Interim Primary Drinking Water Regulations was found in the majority of wells sampled throughout Sarasota County. Highest levels were found areally near the coast or near rivers and vertically in the Tamiami-upper Hawthorn aquifer where...
Hydrologic description of the Tamarack Wildlife area and vicinity, Logan County, Colorado, and simulated effects of possible water-management activities
A.W. Burns
1985, Water-Resources Investigations Report 85-4014
The stream-aquifer system of the Tamarack Wildlife Area and vicinity in Logan County, Colorado, is described using analyses of water level, water temperature, and specific conductance data. Correlation analysis indicated that water levels in the flood plain relate better to those in the river than those in the upgradient valley...
Habitat Suitability Index Models and Instream Flow Suitability Curves: American shad
David J. Stier, Johnie H. Crance
1985, FWS/OBS 82/10.88
INTRODUCTION The American shad, an anadromous species, is the largest member of the herring family (Clupeidae) and is native to North America (Talbot and Sykes 1958; Hildebrand 1963; Walburg and Nichols 1967). Historically, the commercial fishery for American shad on the Atlantic coast was widespread and intense; in 1896 the estimated catch...
Techniques for estimating flood peak discharges for unregulated streams and streams regulated by small floodwater retarding structures in Oklahoma
R. L. Tortorelli, D. L. Bergman
1985, Water-Resources Investigations Report 84-4358
Statewide regression relations for Oklahoma were determined for estimating peak discharge of floods for selected recurrence intervals from 2 to 500 years. The independent variables required for estimating flood discharge for rural streams are contributing drainage area and mean annual precipitation. Main-channel slope, a variable used in previous reports, was...
Preliminary assessment of the ground-water resources of the alluvial aquifer, White River valley, Rio Blanco County, Colorado
W. P. Van Liew, M.L. Gesink
1985, Water-Resources Investigations Report 84-4307
A preliminary study of the alluvial aquifer in the White River Valley was conducted to assess aquifer extent and the occurrence , availability, and chemical quality of water in the aquifer. The aquifer in the study area underlies 35 square miles. Aquifer width ranges from 0.1 to 1.5 miles and...
Codes for the identification of aquifer names and geologic units in the United States and the Caribbean outlying areas
Water Resources Division, U.S. Geological Survey
1985, Circular 878-C
This standard provides codes to be used for the identification of aquifer names and geologic units in the United States, the Caribbean and other outlying areas. Outlying areas include Puerto Rico, the Virgin Islands, American Samoa, the Midway Islands, Trust Territories of the Pacific Islands, and miscellaneous Pacific Islands. Each...
