Ground-water pumpage from the Columbia Plateau Regional Aquifer System, Oregon, 1984 Ground-water pumpage from the Columbia Plateau Regional Aquifer System, Oregon, 1984
Groundwater pumpage was estimated for 1984 for an area of about 8,000 sq mi in north-central Oregon. Pumpage data were collected from irrigation, industrial and public supply users and analyzed as part of the Columbia Plateau Regional Aquifer System Analysis (RASA) study. Groundwater is pumped from Tertiary basalts and interflow material of the Columbia River Basalt Group and the...

Water quality of the Malheur Lake system and Malheur River, and simulated water-quality effects of routing Malheur Lake water into Malheur River, Oregon, 1984-85 Water quality of the Malheur Lake system and Malheur River, and simulated water-quality effects of routing Malheur Lake water into Malheur River, Oregon, 1984-85
Above average precipitation and runoff between 1980 and 1985 have raised the water-surface elevation of Harney, Mud, and Malheur Lakes in eastern Oregon to the highest levels recorded and have caused mixing and interflow of water among the three lakes. A 50% increase in specific conductance throughout Malheur Lake from 1984 to 1985 resulted from an increase in sodium and chloride...

Appraisal of storm-water quality near Salem, Oregon Appraisal of storm-water quality near Salem, Oregon
Stormwater runoff for the period December 1979 to May 1981, at 13 sites (12 basins) in the vicinity of Salem, Oregon, was sampled and analyzed for water quality. Constituent concentrations for urban storm water were relatively small when compared to samples from Portland and Medford, Oregon and to samples from Denver, Colorado. The data indicated that levels of suspended sediment...

Water-quality variations in the Bull Run Watershed, Oregon, under 1978 to 1983 management conditions Water-quality variations in the Bull Run Watershed, Oregon, under 1978 to 1983 management conditions
During the period October 1978 to September 1983, the U.S. Geological Survey, in cooperation with the City of Portland (Oregon) Water Bureau, conducted a study in the Bull Run River basin to define the hydrologic characteristics of the basin, and to examine relations between basin characteristics (both natural and man-made) and stream water quality and quantity within the basin...

Flood hazards along the Toutle and Cowlitz rivers, Washington, from a hypothetical failure of Castle Lake blockage Flood hazards along the Toutle and Cowlitz rivers, Washington, from a hypothetical failure of Castle Lake blockage
A recent evaluation of groundwater and material in the blockage impounding Castle Lake shows that the blockage is potentially unstable against failure from piping due to heave and internal erosion when groundwater levels are seasonally high. There is also a remote possibility that a 6.8 or greater magnitude earthquake could occur in the Castle Lake area when groundwater levels are...

Analysis of fixed-station water-quality data in the Umpqua River basin, Oregon Analysis of fixed-station water-quality data in the Umpqua River basin, Oregon
An appraisal of surface water quality in the Umpqua River basin was made using existing monthly data collected by the Oregon Department of Environmental Quality and the U.S. Geological Survey in cooperation with the Douglas County Water Resources Survey. This appraisal was limited to interpretation of instantaneous monthly water quality data collected in the Umpqua River basin from water...

Plan of study for the Regional Aquifer-System Analysis, Columbia Plateau, Washington, northern Oregon, and northwestern Idaho Plan of study for the Regional Aquifer-System Analysis, Columbia Plateau, Washington, northern Oregon, and northwestern Idaho
The U.S. Geological Survey began a 4-year study of the regional aquifer system underlying the Columbia Plateau, in central and eastern Washington, northern Oregon, and northwestern Idaho in October 1983, as part of the Regional Aquifer System Analysis program. The study will describe the geohydrology, geochemistry, and quality of water in the Columbia River Basalt Group, the Miocene...

Preliminary study of the water-temperature regime of the North Santiam River downstream from Detroit and Big Cliff dams, Oregon Preliminary study of the water-temperature regime of the North Santiam River downstream from Detroit and Big Cliff dams, Oregon
A riverine-temperature model and associated data-collection system were developed to help the Corps of engineers determine cost benefits of selective-withdrawal structures for future use with dams on the Willamette River System. A U.S. Geological Survey Lagrangian reference frame, digital computer model was used to simulate stream temperatures on the North Santiam River downstream of the
