Fish Sampling on the Lower Snake River
USGS biologist Terry Maret (left) joins a colleague from Idaho Power Company for cooperative fish sampling on the lower Snake River near Murphy, ID. Fish tissue samples were collected from selected fish to analyze for the presence of mercury as part of a monitoring program the USGS is conducting in cooperation with the City of Boise.

Coeur dAlene Basin Environmental Monitoring Program
The South Fork Coeur d'Alene River near Kellogg, Idaho has been impacted by historical mining activites. Since 2004, the USGS, in cooperation with the Environmental Protection Agency, has maintained a water-quality monitoring program in the Coeur d'Alene and Spokane River basins of northern Idaho and eastern Washington.

Total Phosphorus Mass Balance Models for the Lower Boise River
USGS hydrologic technician Alvin Sablan calibrates an acoustic Doppler current profiler before collecting a discharge measurement on the Boise River near Caldwell, Idaho. The discharge measurement and other data were used to develop total phosphorus mass balance models for the lower Boise River.

Water-Quality Study in Historical Idaho Mining District
The so-called Glory Hole on the East Fork of the South Fork Salmon River in the historical Stibnite Mining District of central Idaho. A USGS water-quality study found that the Glory Hole acts as a sediment trap, particularly at high streamflow.

Installing Rapid Deployment Streamgage on Boise River near Parma, ID
Beginning April 26, the Boise River of southwestern Idaho reached flood stage. The USGS responded by installing three rapid deployment streamgages on bridges near Eagle, Star, and Parma, Idaho to provide additional information to emergency response teams. In this photo USGS hydrologic technicians install a rapid deployment streamgage on the U.S.
