Scientists from the U.S. Geological Survey and Idaho Power Company collected water, sediment, and biological samples from Brownlee Reservoir as part of an ongoing, cooperative study of mercury cycling in the Hells Canyon complex of reservoirs along the Snake River bordering Idaho and Oregon.

On September 19th, 2017 staff from the USGS NM WSC Albuquerque and Las Cruces offices visited a Climate Response Network (CRN) well just on the east side of the Organ Mountains outside of Las Cruces to receive training on integrity testing groundwater wells.

The Maine Office boat, "Miss Q", is parked next to the boat launch on Verona Island, ready to begin data collection on the Penobscot River. The crew was preparing to collect ADCP data (depth and velocity) as well as conductivity, temperature and depth profiles at various locations. In the background is the Penobscot Narrows Bridge and Fort Knox.

Jim Duda, USGS hydrologic technician, installs a Rapid-Deployment Gauge near the Elizabeth River in Norfolk, Virginia, to monitor elevated water levels caused by Hurricane Jose. An RDG is a fully functional streamgage designed to be quickly deployed for real-time data monitoring of a stream or river in emergency situations.

USGS scientist Jimmy Hopkins repairs a streamgage downstream of Addicks reservoir at Buffalo Bayou after flooding from Hurricane Harvey. This gauge is normally accessed on land from a platform on the side of a bridge.

USGS scientists Lisa Ashmore and Lee Bodkin collect water-quality samples on Lake Houston in response to the high flow conditions that resulted from Harvey.

USGS scientist Tom Pistillo services the streamgage at Addicks Reservoir to ensure that accurate reservoir water-level data are being measured, which are critical for helping the U.S. Army Corps of Engineers and Harris County Flood Control District make informed reservoir operation decisions.
