Estimation of ground-water recharge from precipitation, runoff into drywells, and on-site waste-disposal systems in the Portland Basin, Oregon and Washington Estimation of ground-water recharge from precipitation, runoff into drywells, and on-site waste-disposal systems in the Portland Basin, Oregon and Washington
The average recharge rate in the Portland Basin, in northwestern Oregon and southwestern Washington, is estimated to be about 22.0 inches per year. Of that amount, precipitation accounts for about 20.8 inches per year, runoff into drywells 0.9 inches per year, and on-site waste disposal about 0.4 inches per year. Recharge is highest, about 49 inches per year, in the Cascade Range...

Application of a Geographic Information System for regridding a ground-water flow model of the Columbia Plateau Regional Aquifer System, Walla Walla River basin, Oregon-Washington Application of a Geographic Information System for regridding a ground-water flow model of the Columbia Plateau Regional Aquifer System, Walla Walla River basin, Oregon-Washington
Computerized Geographic Information Systems (GIS) have become viable and valuable tools for managing,analyzing, creating, and displaying data for three-dimensional finite-difference ground-water flow models. Three GIS applications demonstrated in this study are: (1) regridding of data arrays from an existing large-area, low resolution ground-water model to a smaller, high resolution grid...

Surface-water-quality assessment of the Yakima River basin in Washington: major-and minor-element data for sediment, water, and aquatic biota, 1987-91 Surface-water-quality assessment of the Yakima River basin in Washington: major-and minor-element data for sediment, water, and aquatic biota, 1987-91
Major- and minor-element concentrations are presented for streambed and suspended sediment, filtered- and unfiltered-water, and aquatic-biota samples collected during 1987-91 from the Yakima River Basin in south-central Washington. The samples were collected as part of the U.S. Geological Survey's National Water-quality Assessment (NAWQA) program which is designed to provide results that...

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...

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...
