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.

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.

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.
