Pesticides in the Lower Clackamas River Basin, Oregon, 2000-01 Pesticides in the Lower Clackamas River Basin, Oregon, 2000-01
In 2000-01, the U. S. Geological Survey sampled the Clackamas River and its major lower-basin tributaries during storm runoff conditions for 86 dissolved pesticides and selected breakdown products. Twenty-seven compounds, including 18 herbicides, 7 insecticides, and 2 pesticide breakdown products, were detected in 18 stream samples. The most commonly detected pesticides, in decreasing...

Water-quality and algal conditions in the Clackamas River basin, Oregon, and their relations to land and water management Water-quality and algal conditions in the Clackamas River basin, Oregon, and their relations to land and water management
In 1998, the U.S. Geological Survey sampled the Clackamas River, its major tributaries, and reservoirs to characterize basic water quality (nutrients, dissolved oxygen, pH, temperature, and conductance), water quantity (water sources within the basin), and algal conditions (biomass and species composition). Sampling locations reflected the dominant land uses in the basin (forest...

Associations among fish assemblage structure and environmental variables in Willamette Basin streams, Oregon Associations among fish assemblage structure and environmental variables in Willamette Basin streams, Oregon
As part of the U.S. Geological Survey's National Water-Quality Assessment Program, fish were collected from 24 selected stream sites in the Willamette Basin during 1993-1995 to determine the composition of the fish assemblages and their relation to the chemical and physical environment. Variance in fish relative abundance was greater among all sites than among spatially distinct reaches...

Water-quality and algal conditions in the North Umpqua River Basin, Oregon, 1992-95, and implications for resource management Water-quality and algal conditions in the North Umpqua River Basin, Oregon, 1992-95, and implications for resource management
This report describes the results of a synoptic water-quality and algal investigation during July 1995 at 36 stream sites in a 1,350 square-mile area of the North Umpqua River Basin, Oregon. The study area includes a headwaters hydroelectric project area, a Wild and Scenic reach in the main stem immediately downstream, and the watersheds of several major tributaries. Additional data from...

Water quality in the Willamette Basin, Oregon, 1991-95 Water quality in the Willamette Basin, Oregon, 1991-95
This report is intended to summarize major findings that emerged between 1991 and 1995 from the water-quality assessment of the Willamette Basin Study Unit and to relate these findings to water-quality issues of regional and national concern. The information is primarily intended for those who are involved in water-resource management. Yet, the information contained here may also...
