Image: A Rainbow Trout Rests Among Substrate in Panther Creek
April 6, 2015

STATUS: Completed

Historically, Idaho has been home to many productive underground and open-pit mining operations. These activities have also produced water quality problems in some areas. One such example is the Blackbird Mine in central Idaho. Following mining operations from the 1940s through the 1960s, Panther Creek and its tributaries were severely damaged by runoff from the...

Mobile River Basin Chart
September 22, 2014

The Mobile River Basin study is one of several NAWQA studies that began in Federal fiscal year 1997 (October 1996). Study planning and design, and analysis of existing data will be done during the first 2 years, which is consistent with all NAWQA studies. After the 2-year planning period, surface- and ground-water and biological data will be collected intensively for 3 years during a high-...

STATUS: Completed

To make scientifically based water-resource decisions, elected officials, water managers, and the general public need additional information about the Wood River Valley aquifer system. A crucial part of this information is an improved understanding of the extent, thickness, and hydraulic properties of the aquifer—a hydrogeologic framework....

Sample site for water-quality assessment
September 9, 2014

STATUS: Completed

A component of groundwater availability is whether the water quality is suitable for a particular use. Elected officials, water managers, and the general public have raised concerns about whether water quality has been affected in developed and agricultural areas by wastewater disposal, fertilizer application, and animal waste.

Eastern Ada County, Idaho

STATUS: Completed

The mining district in the South Fork Coeur d’Alene River valley was among the Nation’s largest producers of silver, lead, zinc, and other metals from the 1880s to the 1980s. These activities have produced large quantities of waste material that contain environmentally hazardous contaminants such as cadmium, lead, and zinc. Much of this material has been...

A dynamic leaf gas-exchange strategy is conserved in woody plants under changing ambient CO2: evidence from carbon isotope discrimination in paleo and CO2 enrichment studies

Rising atmospheric [CO2], ca, is expected to affect stomatal regulation of leaf gas-exchange of woody plants, thus influencing energy fluxes as well as carbon (C), water, and nutrient cycling of forests. Researchers have proposed various strategies for stomatal regulation of leaf gas-exchange that include maintaining a constant leaf internal [CO2...

Assessing the role of climate and resource management on groundwater dependent ecosystem changes in arid environments with the Landsat archive

Groundwater dependent ecosystems (GDEs) rely on near-surface groundwater. These systems are receiving more attention with rising air temperature, prolonged drought, and where groundwater pumping captures natural groundwater discharge for anthropogenic use. Phreatophyte shrublands, meadows, and riparian areas are GDEs that provide critical habitat...
