River Levels

New Hampshire river levels

Live streamflow for 37 gauged New Hampshire reaches, highest first. Where a gauge has a long enough record, the reading is placed against its own history for today's date.

73% of gauged New Hampshire rivers are running below normal for the date, as of October 26, 2026.

Of 33 gauged reaches with a long enough USGS record, 24 are below normal (6 of them much below), 9 are in the normal range, and 0 are above normal (0 of them much above). Normal means the middle half of that gauge's own history for this calendar date.

Streamflow from the U.S. Geological Survey, updated hourly. "Usually today" is the median for this calendar date over the gauge's full record. A gauge tells you how much water is moving, not whether it is fishing well or safe to wade: check the regulations and a current local report before you go. Flood stages and forecasts: NOAA National Weather Service; "Vs normal" is our comparison with the USGS record, not a National Weather Service product.
