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.

Gary Barton (USGS) and Jeff Laufle (U.S. Army Corps of Engineers) carried out a particle size analysis of the surface riverbed material on the right bank (facing downstream) of the Snake River about three miles below Ice Harbor Dam near Burbank, WA.

A rainbow arches over the Owyhee Canyonlands wilderness area at the site of USGS streamgage 13176400, East Fork Owyhee River at Crutcher Crossing, ID. The U.S. Bureau of Land Management will use data from this gage to secure water rights to protect Wild and Scenic Rivers in the wilderness.

This new streamgage, USGS 13176400, East Fork Owyhee River at Crutcher Crossing, ID, will provide critical data the U.S. Bureau of Land Management needs to secure water rights to protect the Owyhee Canyonlands wilderness area.

Earlier this year, Congress provided $6 million in additional funding for the USGS National Streamflow Information Program (NSIP). This streamgage is one of 10 in Idaho now funded by NSIP.
