Upper Klamath Basin Groundwater Studies
Since the late 1990s, USGS has worked to characterize the regional groundwater hydrology of the upper Klamath Basin. Research focuses on collecting data to evaluate the groundwater system and its response to external stresses, and to develop computer models that provide insights for water management. These efforts build on earlier USGS studies going back to the 1950s.
Harney Basin Groundwater Study
In response to increasing groundwater demand and declining groundwater levels in the Harney Basin of southeastern Oregon, the U.S. Geological Survey and Oregon Water Resources Department conducted a groundwater-availability study during 2016–22. Read to learn about the key findings
Estimating Groundwater Budgets for Oregon
Scientists Stephen Gingerich and Adel Haj, Jr. are leading efforts to estimate groundwater budgets across the state. Water hidden beneath the earth’s surface is a vital resource and quantifying its availability is crucial for long-term management. USGS scientists are collaborating with scientists at the Oregon Water Resources Department to gain a better understanding of this valuable resource.
Walla Walla River Basin groundwater-flow system, Oregon-Washington
The Issue: Decades of declining groundwater levels in the Walla Walla River Basin (WWRB), which spans Oregon and Washington, are affecting instream flows for threatened and culturally important fish populations and water availability for competing interests across state lines. The public and state resource management agencies have begun implementing efforts to stabilize groundwater levels and...
Oregon Water Use Program
With the ever-increasing rate of utilization of and competition for water (particularly during periods of drought) accurate, current water-use information is of considerable value. This is particularly so in determining future water availability in hydrologically critical areas and for making sound resource-management decisions. For the Oregon Water Science Center, a viable water-use data...
Groundwater of the Umatilla River Basin
Water management in the arid Umatilla Basin has become increasingly complex in recent years. Competing demands from society for generating hydro-electric power, maintaining and restoring fisheries, restoring watershed health, providing water for growing communities, and increasing agricultural production through irrigation, have put water resources in the Umatilla Basin and throughout the...
Spring Vulnerability Study for Southeastern Oregon
Evaluating Spring Vulnerability to Climate Change on BLM Priority Management Areas in Southeastern Oregon
Klamath Basin Studies
In 1992, the USGS began studying possible causes for the change in trophic status of Upper Klamath Lake. Since then research has expanded to include groundwater, geomorphology, streamflow forecasting, and fish ecology.
Groundwater Elevation and Temperature in Johnson Creek Basin
Water elevation and temperature in groundwater and Johnson Creek at Sycamore, near Portland, OR
Willamette River Studies
Welcome to the Willamette River Study page. Here you will find links to USGS research for the Willamette River and the Willamette River Basin.
Groundwater in the Upper Deschutes Basin, Oregon
Groundwater monitoring in the Deschutes Basin shows water-level declines are larger than might be expected from climate variations alone, raising questions regarding the influence of groundwater pumping, canal lining, and other human influences.
Hydrogeologic and Geothermal Conditions of the Northwest Volcanic Aquifers
Although sparsely populated, this area in southeastern Oregon, northeastern California, northwestern Nevada, and southeastern Idaho has high geothermal heat flow that may be used to generate large amounts of electricity.
