Due to a lapse in appropriations, the majority of USGS websites may not be up to date and may not reflect current conditions. Websites displaying real-time data, such as Earthquake and Water and information needed for public health and safety will be updated with limited support. Additionally, USGS will not be able to respond to inquiries until appropriations are enacted.  For more information, please see www.doi.gov/shutdown

Hydrologic Investigations near the Remote Handled Low-Level Waste Facility

The U.S. Department of Energy has proposed a location for a new facility to store waste at the INL. In the unlikely event that waste leaks from the facility, it will be important to monitor whether the contamination reaches the aquifer and baseline information is need before the facility is built.

Because we need to know how water and contaminants may travel through the aquifer, we need...

Naval Reactors Facility Groundwater-Quality Monitoring

As part of the Comprehensive Environmental Response Compensation and Liability Act, it is important to evaluate the effect of Naval Reactors Facility (NRF) activities on the water quality of the eastern Snake River Plain aquifer.

Wood River Valley Groundwater-Flow Model

Rapid population growth in the Wood River Valley since the 1970s has caused concern about the long-term sustainability of the groundwater resource. Water-resource planners and managers, as well as other decision makers, need a tool for water rights administration and water-resource management and planning.

Microplastics in Urban Streams of the Northeast Region

Microplastics in the environment are of increasing concern among resource managers and ecologists. With global production of plastic topping 300 million metric tons in 2015, research in fresh and marine waters throughout the world has implicated urban runoff, wastewater treatment effluent, and litter breakdown as major sources of microbeads and synthetic pieces and fibers that are slow to...

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...

Reconstructing Flow History From Riparian Tree Rings

Aquatic Systems Branch scientists analyze rings of riparian trees relating tree growth and establishment to historical flow. We then use the tree rings to reconstruct the flow in past centuries. Flow reconstructions discover the frequency and magnitude of past droughts and floods—information that is essential for management of rivers and water supplies. We also use downscaled climate...

Upper 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.

Monitoring Mercury in Fish Tissue, Boise and Snake Rivers and Brownlee Reservoir

To meet National Pollution Discharge Elimination System (NPDES) permitting requirements, the City of Boise will be responsible for collecting fish tissue samples for mercury analysis upstream of and downstream of their wastewater treatment facilities discharging to the lower Boise and Snake Rivers.

Mercury is a naturally occurring element that ultimately makes its way into aquatic...

Groundwater-Flow Model for the Treasure Valley and Surrounding Area

in partnership with the Idaho Department of Water Resources (IDWR) and Idaho Water Resource Board (IWRB), we will construct a numerical groundwater-flow model of the Treasure Valley and surrounding area. Resource managers will use the model to simulate potential anthropogenic and climatic effects on groundwater for water-supply planning and management. As part of model construction, the...

Wood River Valley Aquatic Biology and Habitat Assessment

Blaine County’s population nearly quadrupled from about 5,700 to 22,000 people between 1970 and 2010. Residents and resource managers of the Wood River Valley of south-central Idaho are concerned about the potential effects that population growth and the expected increased demand for water might have on the quantity and quality of the valley’s ground and surface waters. Increased water use has...

Selenium in the Blackfoot River Watershed

The upper Blackfoot River receives runoff from 12 large phosphate mines. Shale waste rock that is a byproduct of mining is highly enriched in naturally occurring selenium. At optimal concentrations, selenium can be a positive nutrient and antioxidant in mammals and fish. At elevated concentrations, however, it can damage fish and animal immune systems. As early as 1996, livestock deaths...

Identifying Bull Trout Migration in the Upper Boise River Basin

In 1999, the U.S. Fish and Wildlife Service (FWS) listed the bull trout (Salvelinus confluentus) as a threatened species. In 2010, the FWS designated critical habitat for the bull trout, including the upper Boise River basin. The Bureau of Reclamation (Reclamation) operates three reservoirs on the upper Boise River for irrigation and flood control. Reclamation and FWS have a need to understand...
