Reconnaissance of water-quality characteristics of streams in the City of Charlotte and Mecklenburg County, North Carolina
W.H. Eddins, J. K. Crawford
1984, Water-Resources Investigations Report 84-4308
In 1979-81, water samples were collected from 119 sites on streams throughout the City of Charlotte and Mecklenburg County, North Carolina, and were analyzed for specific conductance, dissolved chloride, hardness, pH, total alkalinity, total phosphorus, trace elements, arsenic, cadmium, chromium, copper, iron, lead, manganese, mercury, silver, and zinc and biological...
Nitrogen, sulfate, chloride, and manganese in ground water in the alluvial deposits of the South Platte River Valley near Greeley, Weld County, Colorado
N. G. Gaggiani
1984, Water-Resources Investigations Report 84-4088
Ground water from the valley-fill deposits of the South Platte River Valley and its tributaries is used extensively for agriculture in the study area, about 10 miles east of Greeley and about 50 miles northeast of Denver, Colorado. The valley-fill deposits, which consist of alluvial and terrace deposits, are in...
Habitat Suitability Index Models: American black duck (wintering)
James C. Lewis, Russell L. Garrison
1984, FWS/OBS 82/10.68
INTRODUCTION The American black duck, commonly known as the black duck, is migratory and has a wide geographic range. American black ducks breed from Cape Hatteras, North Carolina, west to the Mississippi River and north through the eastern Canadian boreal forest (Bellrose 1976). The winter range extends from the Rio Grande...
Habitat Suitability Index Models and Instream Flow Suitability Curves: Warmouth
Thomas E. McMahon, Glen Gebhart, O. Eugene Maughan, Patrick C. Nelson
1984, FWS/OBS 82/10.67
The wa rmouth (Lepomi s gul osus) occurs naturally throughout the central and southeastern United States. It is distributed throughout Kansas, Iowa, and Missouri, north to southern Wisconsin, lower Michigan, Lake Erie, and western Pennsylvania, and south to Florida and west through the Gulf States to the Rio Grande (Hubbs...
The Water Resources Division water level recorder rental program; history and operation
S.R. Jeffers, C. R. Wagner
1984, Open-File Report 84-735
The U.S. Geological Survey introduced a new water level recorder in the early 1960 's to automate computation of streamflow records. At the same time it developed a rental program as a means of providing the recorders to field offices. This report documents the experience gained over the past 20...
Preliminary study of the aquifers of the lower Mesilla Valley in Texas and New Mexico by model simulation
J. S. Gates, D. E. White, E. R. Leggat
1984, Water-Resources Investigations Report 84-4317
The aquifers in the lower Mesilla Valley of Texas and New Mexico provide water for irrigation, industrial use, and municipal supply. At present (1984), the shallow aquifer is used principally for irrigation. The medium-depth aquifer (the top of which is about 160 to 260 feet below land surface) and deep...
Magnitude and frequency of flood volumes for urban watersheds in Leon County, Florida
M.A. Franklin
1984, Water-Resources Investigations Report 84-4233
Techniques are provided for estimating runoff magnitudes for urban-flow streams in Leon County, Florida, for recurrence intervals of 2, 5, 10, 25, 50, 100, and 500 years. Synthetic runoff volumes were generated by using a calibrated lumped-parameter rainfall-runoff model, pan evaporation data from Milton, Florida, and long-term unit rainfall records...
Water resources data, Alabama water year 1983
H.C. Rollins, F.C. Sedberry, E.G. Ming, J.W. Tucker
1984, Water Data Report AL-83-1
Water resources data for the 1983 water year consist of records of stage, discharge, and water quality of streams; stage and contents of lakes and reservoirs; and water levels and water quality of ground-water wells. This report contains records for water discharge at 84 gaging stations; stage only at 23...
Water resources data, Arizona water year 1982
Natalie D. White, W. B. Garrett
1984, Water Data Report AZ-82-1
Water resources data for the 1982 water year for Arizona consist of records of stage, discharge, and water quality of streams; stage, contents, and water quality of lakes and reservoirs; measurements of ground-water levels; and quality of water from selected wells. Also included are discharge data for crest-stage partial-record stations...
