Stream and tide gauges (sometimes spelled gages) are devices which measure changes in water levels relative to a specified height reference through the use of sensors. While gauges are relied upon to provide information on cyclical conditions such as tidal changes, they also play a pivotal role in predicting less common events such as when a river reaches flood stage (the flood stage of the Pawcatuck River is 7.0 feet). A flood stage is the height at which water has risen significantly enough to be considered a flood event. Locally, there is one tidal gauge located in Watch Hill Cove and one stream gauge in the Pawcatuck River. The stream gauge is located between Canal Street in Westerly and Stillman Avenue in the neighboring Town of Stonington.
