D. S. Snavely, J. F. Williams
1985, Water-Resources Investigations Report 84-4246
Nassau County, New York depends upon ground water for its freshwater supply. The primary water uses are for public-water supply and industrial-commercial purposes, which together accounted for 202 Mgal/d (million gallons per day) in 1975. Public-water suppliers withdrew 85 percent of their water from the Magothy Formation. About 133 Mgal/d...

Calibration procedure for a daily flow model of small watersheds with snowmelt runoff in the Green River coal region of Colorado
J. M. Norris, R. S. Parker
1985, Water-Resources Investigations Report 83-4263
A calibration procedure was developed for the U.S. Geological Survey 's Precipitation-Runoff Modeling System for watersheds in which snowmelt is the major contributor to runoff. The model uses daily values of air temperature and precipitation as input and the output is mean daily discharge. The procedure appears sufficient to calibrate...

A study of the Stony Fork basin in southern Fayette County, Pennsylvania, from 1977 through 1980 determined the impacts of surface coal mining on surface-water quality. Stony Fork was sampled at six sites, during which time the area of surface mines increased from 0.5 to 5.5 percent of the study...
Time of travel, water quality, and bed-material quality in the Cuyahoga River within the Cuyahoga Valley National Recreation area, Ohio
C.J. Childress
1985, Water-Resources Investigations Report 85-4065
Three studies were conducted in the Cuyahoga Valley National Recreation by the U. S. Geological Survey to (1) establish the relationship between time of travel and discharge through the park reach of the Cuyahoga River, (2) characterize water quality of the Cuyahoga River within the park over a 24-hour period,...
Quality of ground water in Monitor and Williams Townships, Bay County, Michigan

1985, Water-Resources Investigations Report 85-4110
Migration of mineralized water from abandoned subsurface coal mines in Monitor and Williams Townships was thought by many residents to have affected the quality of domestic ground-water supplies in the area. To investigate the possibility, wells were installed to obtain geologic data and water samples for chemical analysis; analysis also...

A method for estimating mean and low flows of streams in national forests of Montana
Charles Parrett, J. A. Hull
1985, Water-Resources Investigations Report 85-4071
Equations were developed for estimating mean annual discharge, 80-percent exceedance discharge, and 95-percent exceedance discharge for streams on national forest lands in Montana. The equations for mean annual discharge used active-channel width, drainage area and mean annual precipitation as independent variables, with active-channel width being most significant. The equations for...
