Massachusetts and Rhode Island FloodWatch

These maps show the location of streamgages where the water level is currently at or above flood stage (depicted as a black triangle) or at high flow (depicted as blue circles). The high flow conditions are expressed as percentiles that compare the current (i.e., within the past several hours) instantaneous flow value to historical daily mean flow values for all days of the year. Flood conditions may be more extensive than shown because the National Weather Service (NWS) has not identified a flood stage at all USGS streamgaging sites. The most complete depiction of streamgages at or above flood stage is on the NWS River Observations Map.
