Surface-water-quality assessment of the Yakima River basin in Washington: Analysis of major and minor elements in fine-grained streambed sediment, 1987 Surface-water-quality assessment of the Yakima River basin in Washington: Analysis of major and minor elements in fine-grained streambed sediment, 1987
Fine-grained streambed sediment from the Yakima River Basin was sampled from 448 locations and analyzed for 45 elements. Anomalous major- and minor-element concentrations were based on baseline values established from element concentrations in streambed sediment in the basin. The largest number of anomalies occurred for antimony, arsenic, cerium, copper, and zinc; at least 10 percent of...

Evaluation of organic compounds and trace elements in Amazon Creek Basin, Oregon, September 1990 Evaluation of organic compounds and trace elements in Amazon Creek Basin, Oregon, September 1990
Water and bottom sediment were collected from Amazon Creek, Oregon during a summer low-flow condition and analyzed for different classes of organic compounds, including many from the U.S. Environmental Protection Agency's priority pollutant list. Bottom sediment also was analyzed for trace elements typically associated with urban runoff. Trace-element concentrations in the less than 63...

Estimated average annual ground-water pumpage in the Portland Basin, Oregon and Washington 1987-88 Estimated average annual ground-water pumpage in the Portland Basin, Oregon and Washington 1987-88
Data for ground-water pumpage were collected during an inventory of wells in 1987-88 in the Portland Basin located in northwestern Oregon and southwestern Washington. Estimates of annual ground-water pumpage were made for the three major categories of use: public supply, industry, and irrigation. A large rapidly expanding metropolitan area is situated within the Portland Basin, along...

A review of possible causes of nutrient enrichment and decline of endangered sucker populations in Upper Klamath Lake, Oregon A review of possible causes of nutrient enrichment and decline of endangered sucker populations in Upper Klamath Lake, Oregon
Upper Klamath Lake, and the connecting Agency Lake, is a large (140 square mile) lake in south-central Oregon. The lake has a recent history of long-duration, near-monoculture, blue-green algal blooms of Aphanizomenon flos-aquae. Typically, the algal bloom causes nuisance and detrimental conditions, including a deep-green "pea soup" appearance, from mid-May to late October. Accompanying...

The dynamic relationship between ground water and the Columbia River: Using deuterium and oxygen-18 as tracers The dynamic relationship between ground water and the Columbia River: Using deuterium and oxygen-18 as tracers
Deuterium and oxygen-18 were used as natural tracers to investigate the hydraulic relationship between the Columbia River and the Blue Lake gravel aquifer near Portland, Oregon. A time series of stable-isotope data collected from surface and ground waters during a March 1990 aquifer test confirms that the river and aquifer are hydraulically connected. Calculations based on simple mixing...
