New England Flood Information

Science Center Objects

The USGS delivers continuous streamflow, stage (water-level), and tide data to help emergency managers and other decision makers protect life and property caused by floods and other water-related hazards.

The USGS New England Water Science Center maintains nearly 450 streamgages that collect data to determine the amount of water flowing in rivers and streams in Connecticut, Maine, Massachusetts, New Hampshire, Rhode Island, and Vermont. The Water Science Center also maintains about 15 tide gages along the coast of New England.

Nationwide, the USGS operates and maintains about 8,000 streamgages, which deliver near real-time data to the public.

Automatic alerts can be sent to mobile devices when streamflow of river or tide stage (water levels) reach user defined thresholds, such as a National Weather Service defined flood stage. These alerts help emergency managers and the public assess potentially hazardous conditions nearby a streamgage, stage-only gage, or tide gage.

USGS WaterNow sends data showing current water conditions directly to your mobile device.

USGS WaterAlert automatically sends email or SMS text messages when certain parameters at a USGS real-time data-collection station, exceed user-defined thresholds.

USGS Flood Information provides additional information about USGS flood science.
