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...
