Walla Walla Groundwater

The Issue: Within the states of Washington and Oregon, the 1,777 mi2 Walla Walla River Basin (WWRB) is a complex hydrogeologic system with long-term water-level declines in regional aquifers and insufficient instream flows required for threatened and culturally important fish populations. The public and state resource management agencies need an improved...

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-...

Upper Klamath Basin Groundwater Studies

Since the late 1990s the USGS has worked to characterize the regional groundwater hydrology of the upper Klamath Basin. Research focuses on collecting data to help evaluate the state of the groundwater system and its response to external stresses, and to develop computer models to provide insights useful for water management. These efforts build on earlier USGS studies in the basin going back...

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.

Columbia Plateau Groundwater Availability Study

The Columbia Plateau Regional Aquifer System (CPRAS) covers about 44,000 square miles of eastern Oregon and Washington and western Idaho. The primary aquifers are basalts of the Columbia River Basalt Group and overlying basin-fill sediments. Groundwater availability issues in the basin include: 1) widespread water-level declines caused by pumping, 2) reduction in base flow to rivers and...
