River and stream flow data, both historical and current, are provided by a system of gages maintained by the U.S. Geological Survey and the U.S. Army Corps of Engineers:

Information on current and projected flows at Connecticut River mainstem dams is available through TransCanada Hydro Northeast.

The topic of river flow is gaining increased attention from policy makers and river watchers. Flow is the muscle of a river that turns generators, provides habitat, and renews biological life -- but can rearrange it too in a flood or drought.

New flood plain mapping is currently underway for the NH & VT portion of the Connecticut River from the White River Junction area to Vernon Dam, sponsored by the Federal Emergency Management Agency. For more information, contact the New England Floodplain and Stormwater Managers Association.
