Multiparameter Display and Data Sheet

USGS scientists used this multiparameter display system attached to a water-quality sonde and the accompanying data sheet as they collected water-quality data from the lower Boise River near Veterans Memorial Parkway in Boise, ID. The data collected are being used to develop models of total phosphorus mass balance for the lower Boise River watershed that are scheduled for

Water-Quality Study in Historical Idaho Mining District

The so-called Glory Hole on the East Fork of the South Fork Salmon River in the historical Stibnite Mining District of central Idaho. A USGS water-quality study found that the Glory Hole acts as a sediment trap, particularly at high streamflow.

Installing Rapid Deployment Streamgage on Boise River near Parma, ID

Beginning April 26, the Boise River of southwestern Idaho reached flood stage. The USGS responded by installing three rapid deployment streamgages on bridges near Eagle, Star, and Parma, Idaho to provide additional information to emergency response teams. In this photo USGS hydrologic technicians install a rapid deployment streamgage on the U.S. Highway 95 bridge near

Kootenai River Habitat Restoration

Constructed channel features and changes in the Phase 1A side channel restoration area of the Kootenai River near Bonners Ferry, Idaho. The Kootenai Tribe of Idaho is managing a large-scale, ecosystem-based river habitat restoration effort that will be implemented over a period of 10 to 15 years across a 55-mile reach of the Kootenai River in northern Idaho. The USGS is

Blackfoot River, Southeastern Idaho

Sceintists from the U.S. Geological Survey and the Idaho Department of Environmental Quality combined and analyzed data from two separate water-quality monitoring efforts in the upper Blackfoot River of southeastern Idaho. The river receives runoff from 12 phosphate mining opoerations, and waste rock material from mining is highly enriched in naturally occuring selenium.

Bedload Sampling, Kootenai River, Idaho

USGS hydrologic technicians retrieve a bedload sample from the Kootenai River near Bonners Ferry, Idaho. The USGS compared the results of bedload and suspended sediment sampling with data collected from acoustic devices submerged in the river. The results were published in USGS Scientific Investigations Report 2015-5169.
