Water-quality data from long-term (24 years), fixed- station monitoring at the Cape Fear River at Lock 1 near Kelly, N.C., and various measures of basin development are correlated. Subbasin population, number of acres of cropland in the subbasin, number of people employed in manufacturing, and tons of fertilizer applied in the basin are considered as measures of basinwide development activity. Lin

A unique facility capable of recirculating and continuously measuring the transport rates of sediment particles ranging in size from about 1 to 75 millimeters in diameter was designed and used in an extensive program involving the calibration of bedload samplers. The facility consisted of a 9-footwide by 6-foot-deep by 272-foot-long rectangular channel that incorporated seven automated collection

Although the uptake, storage, and elimination of contaminants by naiad mollusks has been studied, relatively little information is available on toxicity. Contaminants appear to have destroyed some populations directly by exerting toxic effects, or indirectly by causing or contributing to the elimination of essential food organisms or host fish. The most frequently studied contaminants are Cd, Cu,

The effects of dewatering a proposed zinc and copper mine on water levels of four lakes near Crandon, Wisconsin, were predicted by use of a digital water-budget model of the lakes. The average lake-stage reduction predicted by the model for expected ground-water levels after mine dewatering ranged from 0.21 feet for Duck Lake to 6.9 feet for Little Sand Lake. These stage reductions assume that no

Water-quality data were collected at five sites on Orwell Reservoir and two sites on the Otter Tail River, at the inflow and outflow points of the reservoir. The data, collected from April 1983 to July 1966, consist mainly of streamflow and nutrient concentrations at the river sites and nutrient concentrations, alkalinity, Secchi-disk transparency, phytoplankton counts, chlorophyll concentrations,

The fate of a single i.v. dose (120 μg/kg) of the piscicide [14C]rotenone was evaluated in rainbow trout for periods up to 72 h after dosing. Rotenone was rapidly cleared from the plasma; less than 2% of the dose remained in the plasma compartment after 20 min. The highest concentrations of rotenone residues (% dose/g tissue) were in the hepatobiliary system, bile, intestine, and in heart, lateral
