Groundwater budget for the Mountain Home area, southern Idaho, 2022–23 Groundwater budget for the Mountain Home area, southern Idaho, 2022–23
The U.S. Geological Survey, with funding from the Idaho Department of Water Resources, developed a groundwater budget for the Mountain Home area in southern Idaho for irrigation year 2023 (November 1, 2022–October 31, 2023). This study focused on the water balance across the Cinder Cone Butte Critical Groundwater Area (CGWA), Mountain Home Groundwater Management Area (GWMA), and the rest...
Aquatic reflectance derived from Sentinel-2 Multispectral Imager data for inland waters in the conterminous United States Aquatic reflectance derived from Sentinel-2 Multispectral Imager data for inland waters in the conterminous United States
Satellite-based earth observation is a robust tool for tracking change in ecosystems. While terrestrially focused applications of remote sensing have empowered wide adoption for research and management, remote sensing of inland aquatic ecosystems remains comparably nascent. This divergence, in part, stems from the lack of standardized, accessible, and near real-time remotely sensed...
A comparison of non-contact methods for measuring turbidity in the Colorado River A comparison of non-contact methods for measuring turbidity in the Colorado River
Monitoring suspended-sediment concentration (SSC) is essential to better understand how sediment transport could adversely affect water availability for human communities and ecosystems. Aquatic remote sensing methods are increasingly utilized to estimate SSC and turbidity in rivers; however, an evaluation of their quantitative performance is limited. This study evaluates the performance...

INLPO Software
Our science staff has developed a suite of software products designed to enhance research and data analysis capabilities. Each product plays a crucial role in facilitating access to data and analyses relevant to groundwater and surface water monitoring in the region.
Mercury Cycling in the Hells Canyon Complex
The Hells Canyon Complex (HCC) is the largest privately owned hydroelectric power complex in the United States. Upstream are millions of acres of irrigated agricultural lands and Idaho’s largest metropolitan area clustered around the state capital Boise. Downstream lie confluences with the Salmon and Clearwater Rivers, critical habitat for threatened bull trout and fall chinook salmon. Elevated...
Real-Time Pier 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...
