USGS scientist Steve Hannes marks high water marks along the Colorado River after flooding from Hurricane Harvey in Wharton County, Texas.

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.

Planning meeting at the USGS Gulf Coast Office.

USGS field crews made multiple record high flood measurements on Aug. 27, including downstream of Addicks and Barker dam. Flood measurements near Addicks and Barker dam are critical for making public safety decisions, as 1.2 million people live downstream.
