This report presents selected data describing the characteristics of streams upstream from selected points on streams in the Redwood River basin. The points on the streams include outlets of subbasins of about five square miles, sewage treatment plant outlets, and U.S. Geological Survey gaging stations in the basin.

Average annual runoff was computed or estimated for 2,148 hydrologic cataloging units in the United States and Puerto Rico , for the period 1951-80. Runoff was computed from the recorded streamflow at 5,951 U.S. Geological Survey gaging stations. The runoff at more than 3,000 of these stations was estimated by correlation with other nearby stations to adjust for missing data. These runoff data wer

The U.S Geological Survey (USGS) compiled and analyzed existing hydrologic and water-quality data from over 200 stream and estuary stations of the Abemarle-Pamlico estuarine system (A/P) to identify long-term temporal and spatial trends. The dataset included seven stations of the USGS National Stream Quality Accounting Network, two stations of the National Atmospheric Precipitation Deposition moni

Water levels, locations, depths, and aquifers tapped are given for 112 observation wells. Tabulated data include a listing of ground water reports in Michigan, extremes of water levels for calendar year 1988 and for the period of record, pumpage of most major ground-water users in the State, and water-quality data from selected wells. The two largest municipal users of ground water, were the citie

A macrophyte submodel has been incorporated and tested in CE-QUAL-R1, a one-dimensional, vertically averaged model of reservoir water quality. A quasi two-dimensional scheme was necessary to represent the spatial relationship of macrophytes in reservoirs adequately. The macrophyte processes modeled were photosynthesis, dark respiration, excretion and nonpredatory mortality. Process equations for p

Interspecies variability in the metabolism of pentachlorophenol (PCP) was investigated by exposing rainbow trout, fathead minnows, sheepshead minnow, firemouth, and goldfish to water-borne super(14)C-PCP for 64 h. The amounts of metabolites in bile and exposure water were species-dependent; all of the metabolites excreted into the water were sulphate conjugates while bile was enriched in glucu

The accumulation kinetics of pentachlorophenol (PCP) were investigated in rainbow trout (Salmo gairdneri) in the absence and presence of 25 mg/1 salicylamide, an inhibitor of PCP metabolism. After exposure to 5 μg/1 PCP over 1–96 h, the amount of PCP in the whole fish, its concentration in water and the total amount of metabolites (water, whole fish and bile) were measured. Equations for these var

Thirty adult (3.2a??8.6 kg) striped bass Morone saxatilis were tagged with ultrasonic transmitters and tracked for up to 475 d in 9,510-hectare Lake Whitney, a Texas reservoir, to determine seasonal distribution, migration patterns, and water temperatures occupied. Striped bass distribution in summer was limited to an area near the dam, where they survived temperatures as high as 29.0A?C. Tagged f

The objectives of this study were to determine the effectiveness ofchemical treatments of the Ocqueoc River, Michigan, in reducing the number of recently metamorphosed sea lampreys Petromyzon marinus migrating to Lake Huron and to estimate total numbers of migrants produced before and after treatment. Sea lampreys were captured during their downstream migration in a single fyke net fished in the s
