Maine vs normal

How Maine’s rivers compare to normal

Every gauge placed by its own percent of normal, and three years of the statewide trend.

Where every gauge actually sits

One dot per Maine streamgauge, placed by its own percent of normal. The state average is a single line through all of it.

799 daily readings from 45 reporting gauges. Percent of normal is today's statewide discharge against the historical average for the same calendar day — 100% is normal, not "good". The axis tops out at 175%: 13 readings above that — including the 428% peak in Dec 2023 — are drawn along the top edge, so a few flood days cannot flatten three years of everything else. The line breaks in 2 places where the record skips more than five days — those are gaps in reporting, not readings of zero.

About Maine streamflow

What are river levels like in Maine right now?

As of October 16, 2026, Maine rivers are running at 70% of normal across 45 USGS streamgauges, and the Androscoggin River At Rumford is reporting the highest discharge at 3,610 cfs. The full sortable gauge table is below.

Which Maine river is running highest right now?

As of October 16, 2026, the highest discharge in Maine is 3,610 cfs on the Androscoggin River At Rumford. See the sortable gauge table for the full statewide ranking.

Are Maine rivers high or low right now?

Compare the statewide percent-of-normal on this page: above 100% means Maine rivers are running higher than the seasonal average for the date, below 100% means lower (a dry spell or drought). Each gauge also shows its own percent of median.

Where does the Maine streamflow data come from?

The U.S. Geological Survey National Water Information System. USGS streamgauges report continuously (every 15 minutes) and the data is the canonical real-time record for U.S. rivers. Snoflo pulls the latest readings and joins them to a 7-day NOAA weather forecast for each station.

What is cfs?

Cubic feet per second — the standard unit for streamflow. One cfs is about 7.5 gallons per second. Small creeks run at single-digit cfs; the Mississippi at hundreds of thousands.

What does Gauge Height mean?

The water level at the gauge in feet above the reference datum. Used together with discharge to track river state. Flood stage and runnable levels are typically expressed in gauge height (e.g., "flood at 16 ft").

How fresh is the Maine data?

USGS streamgauges report every 15 minutes; Snoflo re-pulls throughout the day. The AI briefing regenerates daily.

Can I get a flow alert for a Maine gauge?

Yes. Save any USGS gauge as a favorite in the Snoflo iOS app, set a discharge or stage threshold (e.g. "alert me when discharge crosses 2,000 cfs"), and you'll get a push the moment it crosses.

Is this a substitute for an NWS flood warning?

No. Snoflo is informational. For flood life-safety decisions always follow guidance from your local NWS forecast office and state emergency management. Snoflo data is one input among several.
