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.

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.

USGS hydrologic technicians Ryan Smith and Rhonda Weakland collect a bedload sediment sample from the Kootenai River near Bonners Ferry, Idaho. The sampling is part of long-term monitirong the USGS is conducting on the Kootenai River to support a river habitat restoriation program undertaken by the Kootenai Tribe of 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.

An acoustic Doppler velocity meter mounted on a track for instream deployment. The USGS deployed devices similar to this on at three monitoring sites on northern Idaho's Kootenai River to estimate sediment concentrations in the spawning habitat of the endangered Kootenai River white sturgeon.
