Assessment of Eutrophication in the Lower Yakima River Basin, Washington, 2004-07 Assessment of Eutrophication in the Lower Yakima River Basin, Washington, 2004-07
In response to concerns that excessive plant growth in the lower Yakima River in south-central Washington was degrading water quality and affecting recreational use, the U.S. Geological Survey and the South Yakima Conservation District conducted an assessment of eutrophication in the lower 116 miles of the river during the 2004-07 irrigation seasons (March - October). The lower Yakima...

Organic Compounds in Clackamas River Water Used for Public Supply near Portland, Oregon, 2003-05 Organic Compounds in Clackamas River Water Used for Public Supply near Portland, Oregon, 2003-05
Organic compounds studied in this U.S. Geological Survey (USGS) assessment generally are man-made, including pesticides, gasoline hydrocarbons, solvents, personal care and domestic-use products, disinfection by-products, and manufacturing additives. In all, 56 compounds were detected in samples collected approximately monthly during 2003-05 at the intake for the Clackamas River Water...

Hydrologic and Water-Quality Conditions During Restoration of the Wood River Wetland, Upper Klamath River Basin, Oregon, 2003-05 Hydrologic and Water-Quality Conditions During Restoration of the Wood River Wetland, Upper Klamath River Basin, Oregon, 2003-05
Restoring previously drained wetlands is a strategy currently being used to improve water quality and decrease nutrient loading into Upper Klamath Lake, Oregon. In this 2003-05 study, ground- and surface-water quality and hydrologic conditions were characterized in the Wood River Wetland. Nitrogen and phosphorus levels, primarily as dissolved organic nitrogen and ammonium (NH4) and...

Phosphorus and nitrogen legacy in a restoration wetland, upper Klamath lake, Oregon Phosphorus and nitrogen legacy in a restoration wetland, upper Klamath lake, Oregon
The effects of sediment, ground-water, and surface-water processes on the timing, quantity, and mechanisms of N and P fluxes were investigated in the Wood River Wetland 57 years after agricultural practices ceased and seasonal and permanent wetland hydrologies were restored. Nutrient concentrations in standing water largely reflected ground water in winter, the largest annual water...

Pesticide Occurrence and Distribution in the Lower Clackamas River Basin, Oregon, 2000-2005 Pesticide Occurrence and Distribution in the Lower Clackamas River Basin, Oregon, 2000-2005
Pesticide occurrence and distribution in the lower Clackamas River basin was evaluated in 2000?2005, when 119 water samples were analyzed for a suite of 86?198 dissolved pesticides. Sampling included the lower-basin tributaries and the Clackamas River mainstem, along with paired samples of pre- and post-treatment drinking water (source and finished water) from one of four drinking water...

Effects of urbanization on stream ecosystems in the Willamette River basin and surrounding area, Oregon and Washington Effects of urbanization on stream ecosystems in the Willamette River basin and surrounding area, Oregon and Washington
This report describes the effects of urbanization on physical, chemical, and biological characteristics of stream ecosystems in 28 watersheds along a gradient of urbanization in the Willamette River basin and surrounding area, Oregon and Washington, from 2003 through 2005. The study that generated the report is one of several urban-effects studies completed nationally by the U.S...

Water Quality and Algal Data for the North Umpqua River Basin, Oregon, 2005 Water Quality and Algal Data for the North Umpqua River Basin, Oregon, 2005
The upper North Umpqua River Basin has experienced a variety of water-quality problems since at least the early 1990's. Several reaches of the North Umpqua River are listed as water-quality limited under section 303(d) of the Clean Water Act. Diamond Lake, a eutrophic lake that is an important source of water and nutrients to the upper North Umpqua River, is also listed as a water...

Water Quality in the Yakima River Basin, Washington, 1999-2000 Water Quality in the Yakima River Basin, Washington, 1999-2000
This report contains the major findings of a 1999?2000 assessment of water quality in streams and drains in the Yakima River Basin. It is one of a series of reports by the NAWQA Program that present major findings on water resources in 51 major river basins and aquifer systems across the Nation. In these reports, water quality is assessed at many scales?from large rivers that drain lands

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...
