USGS Rapid Deployment Gages (RDGs)

Science Center Objects

USGS Rapid Deployment Gages (RDGs) are fully-functional streamgages designed to be deployed quickly and temporarily to measure and transmit stream stage data in emergency situations.

    The speed with which Rapid Deployment Gages (RDGs) can be installed allows the USGS to:

    • augment gage networks during coastal or riverine flooding by adding additional temporary locations to the network.
    • provide situational awareness and support to emergency managers.
    • maintain data flow when streamgaging equipment is damaged.

    The design and uses of RDGs vary according to the environment where they are installed.
