Science and Products
American Falls Reservoir Bathymetry
In cooperation with the Bureau of Reclamation, we surveyed the bathymetry within an area of about 500 acres of American Falls Reservoir between River Miles 713 and 714 August 6-8, 2019. The bathymetric survey provided high-resolution detail of a proposed treatment area for an aeration system that is being developed to support water quality during the American Falls spillway concrete repair...
Bathymetric Mapping of the Kootenai River
The Kootenai River white sturgeon (Acipenser transmontanus) and other native fish species are culturally important to the Kootenai Tribe of Idaho, but their habitat and recruitment have been affected by anthropogenic changes to the river. The Tribe has undertaken a large-scale restoration project and needs objective...
Evaluating Spatial and Temporal Fine-Scale Movement of Kootenai River White Sturgeon
The U.S. Fish and Wildlife Service has published a plan for recovering the endangered Kootenai River white sturgeon. This study supports the objectives of that plan by quantifying white sturgeon habitat preference within a recently restored reach of the...
Real-Time Bridge Scour Monitoring and Evaluation
The most common cause of bridge failure is scour, when high-velocity streamflow scours streambed material from around bridge piers and abutments. As of 2017, the National Bridge Inventory listed 265 of Idaho's nearly 4,500 bridges (about 6 percent) as "scour critical." When rivers rise quickly, bridge inspectors have little or no time to mobilize and monitor bridges at risk of scour. Real-time...
Kootenai River Sediment Studies
The Kootenai River white sturgeon (Acipenser transmontanus) and other native fish species are culturally important to the Kootenai Tribe of Idaho, but their habitat and recruitment have been affected by anthropogenic changes to the river. White sturgeon and burbot have not successfully spawned in the Kootenai River since the completion of Libby Dam upstream in Montana. In recent years...
Streamflow Evaluation for Water Right Claims for Wild and Scenic Rivers, Owyhee Canyonlands Wilderness
Several river segments in the Owyhee Canyonlands Wilderness have been designated as “Wild and Scenic” under the Omnibus Public Lands Management Act of 2009. This designation is intended to protect the “outstanding remarkable values” (ORVs) in this area—specifically fish and wildlife habitat, scenic and geological features, and recreational opportunities.

Estimating Seepage Rates of Streams, Ponds, and Lakes at the Camas National Wildlife Refuge
The Camas National Wildlife Refuge provides essential resting, feeding, and nesting habitat for waterfowl including migratory birds. A variety of other animals, large and small, are found there, too. Since the refuge was established in 1937, the U.S. Fish and Wildlife Service (USFWS) has been responsible for managing this vital resource.
Traditionally, Camas Creek and groundwater inflow...
Surrogate Technologies for Estimating Suspended Sediment in the Snake and Clearwater Rivers
Because fluvial sediment poses both economic and ecological problems, resource managers need a safe, cost-effective way to measure sediment in streams, particularly in remote areas.
Lower Granite Reservoir Bathymetric and Underwater Video Surveys
Sedimentation of Lower Granite Reservoir, operated by the U.S. Army Corps of Engineers, affects commercial navigation and reservoir storage capacity. Some groups are concerned that dredging the reservoir to remove excess sediment may negatively affect endangered species such as steelhead and salmon.
Lower Granite Reservoir Bed Sediment Coring and Analysis
Some groups are concerned that dredging the reservoir and the confluence of the Snake and Clearwater Rivers to remove excess sediment may mobilize contaminants in sediment that could negatively affect endangered species such as steelhead and salmon.
Assessment of bridge scour countermeasures at selected bridges in the United States, 2014–18
Erosion of the streambed, known also as scour, around pier 3 of the New York State Thruway bridge over Schoharie Creek caused the pier to fail, which ultimately resulted in bridge failure during the flooding event of April 5, 1987. The Federal Highway Administration (FHWA) responded to the need for better guidance on the evaluation of bridge scour...

Defining the limits of spectrally based bathymetric mapping on a large river
Remote sensing has emerged as a powerful method of characterizing river systems but is subject to several important limitations. This study focused on defining the limits of spectrally based mapping in a large river. We used multibeam echosounder (MBES) surveys and hyperspectral images from a deep, clear-flowing channel to develop techniques for...
