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...

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...

Water Temperature Modeling in the Middle Fork Willamette and South Santiam River Basins

Hills Creek, Lookout Point, and Dexter Dams are located on the Middle Fork Willamette River upstream of Eugene in western Oregon, and are important resources managed by the U.S. Army Corps of Engineers (USACE) for flood control, hydroelectric power, recreation, navigation, and irrigation. On the South Santiam River east of Albany in western Oregon, Green Peter and Foster Dams provide functions...

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.
