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.

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.
During the summer of 2014, water levels in 177 monitoring wells at the Idaho National Laboratory reached record lows. In this report, USGS hydrologists Roy Bartholomay and Brian Twining examine hydrologic influences on water-level declines and how continuing declines might affect wells and pumps.
