A high-water mark tag nailed to a tree trunk with visible debris. The debris that adheres to the tree is the physical evidence of how high the flood waters rose during the flood event; when the waters recede, the debris transported by the flood waters that was floating on the top of the water sticks to the tree.
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 434 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 13 tide 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 WaterAlert automatically sends email or SMS text messages when certain parameters at a USGS real-time data-collection station, exceed user-defined thresholds.
