Willamette Basin Groundwater Study Completed
By Oregon Water Science Center
October 10, 2000
The U.S. Geological Survey (USGS) studies the water resources of the Willamette River Basin. Here you will find a description of the study, as well as information and data resulting from this work.
The USGS has collected and compiled groundwater data for the Willamette River Basin, Oregon. This research includes data for 1,234 field located water wells and 6 springs, hydrographs of water-level fluctuations during various time periods for 265 wells, borehole geophysical data for 16 wells, and water-chemistry analyses from 125 wells and 6 springs. These data, as well as data for 4,752 additional fieldlocated wells and 1 spring, are archived online.

Simulation of groundwater flow and the interaction of groundwater and surface water in the Willamette Basin and Central Willamette subbasin, Oregon
Full appropriation of tributary streamflow during summer, a growing population, and agricultural needs are increasing the demand for groundwater in the Willamette Basin. Greater groundwater use could diminish streamflow and create seasonal and long-term declines in groundwater levels. The U.S. Geological Survey (USGS) and the Oregon Water Resources Department (OWRD) cooperated in a study to develo

Ground-water hydrology of the Willamette basin, Oregon
The Willamette Basin encompasses a drainage of 12,000 square miles and is home to approximately 70 percent of Oregon's population. Agriculture and population are concentrated in the lowland, a broad, relatively flat area between the Coast and Cascade Ranges. Annual rainfall is high, with about 80 percent of precipitation falling from October through March and less than 5 percent falling in July an

Heat as a tool for studying the movement of ground water near streams
Stream temperature has long been recognized as an important water quality parameter. Temperature plays a key role in the health of a stream’s aquatic life, both in the water column and in the benthic habitat of streambed sediments. Many fish are sensitive to temperature. For example, anadromous salmon require specific temperature ranges to successfully develop, migrate, and spawn [see Halupka and
Estimates of ground-water recharge, base flow, and stream reach gains and losses in the Willamette River basin, Oregon
Precipitation-runoff models, base-flow-separation techniques, and stream gain-loss measurements were used to study recharge and ground-water surface-water interaction as part of a study of the ground-water resources of the Willamette River Basin. The study was a cooperative effort between the U.S. Geological Survey and the State of Oregon Water Resources Department. Precipitation-runoff models wer

Origin, extent, and thickness of quaternary geologic units in the Willamette Valley, Oregon
Stratigraphic and chronologic information collected for Quaternary deposits in the Willamette Valley, Oregon, provides a revised stratigraphic framework that serves as a basis for a 1:250,000-scale map, as well as for thickness estimates of widespread Quaternary geologic units. We have mapped 11 separate Quaternary units that are differentiated on the basis of stratigraphic, topographic, pedogenic

Arsenic in ground water of the Willamette Basin, Oregon
In response to increasing demands on ground-water resources in the Willamette Basin, Oregon (fig. 1), the Oregon Water Resources Department (OWRD) and the U.S. Geological Survey (USGS) began a cooperative study of the basin’s ground-water resources in 1996. This study was designed to increase the current understanding of the ground-water resource, and to better characterize the distribution of nat

Analysis of nutrient and ancillary water-quality data for surface and ground water of the Willamette Basin, Oregon, 1980-90
An analysis of historical water-quality data for surface and ground water collected in the Willamette and Sandy River Basins during the 1980-90 water years was performed. For surface water, most data were concentrated at sites on the main stem Willamette River or near the mouths of major tributaries. All seasons were represented. Data for nitrogen and phosphorus species were readily available, but
