Flow Reports

Anglers and boaters are sometimes caught off guard by the quickly changing flows in the Connecticut River and its tributaries. The rapid changes are unsafe to swimmers and other people who are using the river. There are a number of gauging stations on the river that post river height and/or flows.

Waterline flow forecasts are provided by the controllers of the sites being forecast and are updated in real time. These forecasts are published on Waterline’s Web site. Most river level readings are taken from river gauges that report over the NOAA’s GOES satellite system. These readings are taken directly from the satellite feed and are usually available within two minutes from the time they are transmitted from the gauge.
