Spring Vulnerability Study for Southeastern Oregon
Evaluating Spring Vulnerability to Climate Change on BLM Priority Management Areas in Southeastern Oregon
Willamette River Basin Dissolved Gas Monitoring Network
USGS total dissolved gas (TDG) data help guide spill and discharge management from dams operated along tributaries of the Willamette River.
Groundwater Elevation and Temperature in Johnson Creek Basin
Water elevation and temperature in groundwater and Johnson Creek at Sycamore, near Portland, OR
Johnson Creek Basin Hydrologic Monitoring Study
The USGS provides hydrologic data for the Johnson Creek Basin. Real-time surface-water, water-quality and groundwater data, as well as historic data and analyses, help to improve our understanding of the hydrology of the basin.
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.
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.
A Thermal Mosaic for the Willamette River
The U.S. Army Corps of Engineers operates 12 dams in the Willamette River Basin. The dams alter natural temperature and hydrologic regimes. Unnatural water temperatures can negatively impact all life stages of salmonid fish species. Water temperature in the mainstem Willamette River regularly exceeds the standard of 18.0 °C (64.4 °F) designated for salmon and trout rearing and migration for mid...
Lower Columbia River Dissolved Gas Monitoring Network
USGS total dissolved gas (TDG) data help guide spill and discharge management from dams operated along the lower Columbia River.
Water Quality in Willow Creek Reservoir, Oregon
Blue-green algal blooms in the Willow Creek Reservoir may produce toxins that can be harmful to those that come in contact with them.
North Santiam River Basin Study
The streamflow and water-quality conditions monitored by the USGS in the North Santiam River basin provide valuable information to water resource managers
Nutrient Loading to Lost River and Klamath River Subbasins
The USGS has characterized nutrient concentrations in the Klamath River and Lost River drainages over multiple years, identified spatial and temporal patterns in nutrient and organic carbon concentrations, and quantified surface water nutrient loads entering and exiting the Klamath Project.
Umpqua River Basin Studies
The Wild and Scenic North Umpqua River is one of the highest-quality waters in the State of Oregon, supporting runs of wild salmon, steelhead, and trout. The USGS has been studying water-quality in the Umpqua River Basin since 1998.
