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.
