The USGS Storm Event dashboard allows users to interact with and visualize high-water mark and storm sensor data points, and estimated flood extents from the January and March 2018 Nor’easter storm events. Users can also view the USGS 100-year Stillwater analysisand compare these flood extents to the current FEMA national flood hazard layers.
