The USGS is collecting streamflow, water temperature, and other data from rivers and streams to document the severity of this year’s drought across six western states, including Idaho. The goal of the study is to assess how warmer winter temperatures, reduced mountain snowpack, and a shift in precipitation from snow to rain may affect future water availability.
We've launched a new service to help you stay updated about Idaho's water resources. Each month, we'll summarize significant findings from our hydrologic data networks, announce new studies, and let you know how we're supporting our local, state, Federal, and tribal partners with reliable, unbiased science.

The Brazilian government is working to improve transportation by waterway, but drought and sedimentation are hampering navigation. The U.S. Army Corps of Engineers and the USGS teamed up to provide technical assistance in topographic and hydrographic surveying. The data collected and presented in this report will assist decision making about the São Francisco River.
Our biologists analyzed mercury concentrations in rainbow trout collected from three reservoirs on the Duck Valley Reservation. The work, conducted in cooperation with the Shoshone-Paiute Tribes, will help the Tribes to protect these important sport fisheries.
