Androscoggin River river
Total streamflow across the Androscoggin River was last observed at 11,310 cfs, and is expected to yield approximately 22,433 acre-ft of water today; about 59% of normal. River levels are low and may signify a drought. Average streamflow for this time of year is 19,040 cfs, with recent peaks last observed on 2023-12-20 when daily discharge volume was observed at 146,900 cfs.
Maximum discharge along the river is currently at the Androscoggin River Near Auburn reporting a streamflow rate of 5,000 cfs. However, the streamgauge with the highest stage along the river is the Androscoggin River At Rumford with a gauge stage of 4.13 ft. This river is monitored from 4 different streamgauging stations along the Androscoggin River, the highest being situated at an altitude of 1,249 ft, the Androscoggin River At Errol.

Maximum streamflow discharge by year
The single highest aggregate discharge recorded each year. Spotting the multi-year trend reveals droughts vs. wet cycles long before the headline daily flow does.

Streamflow elevation profile
Each bubble is one gauge along the river, plotted by current streamflow (x-axis) vs elevation (y-axis), sized by gauge stage. Reading top-to-bottom traces the river from headwaters down to its mouth -- you can see flow accumulate as elevation drops.

Androscoggin River
The Androscoggin River runs through New Hampshire and Maine, covering a length of 178 miles. It was once one of the most polluted rivers in the country due to the paper mills that lined its banks, but since the 1970s, extensive cleanup efforts have improved the water quality. The river's hydrology is influenced by several dams, including the Livermore Falls Dam, the Gulf Island Dam, and the Berlin Dam, which provide hydropower and flood control. The river also has several reservoirs, including the Umbagog Lake, the Richardson Lake, and the Aziscohos Lake. Recreational activities such as fishing, hiking, and camping are popular along the river, and the river also supports agricultural activities like irrigation and farming.
Track the Androscoggin River in the Snoflo app
Set per-gauge push alerts (e.g. "alert me when flow at the Russian R Nr Healdsburg crosses 5,000 cfs"), and Snoflo's iOS app pushes the moment USGS reports the crossing.
About the Androscoggin River
Where does the data for the Androscoggin River come from?
Streamflow and gauge stage data are sourced from the U.S. Geological Survey (USGS) National Water Information System. The aggregate flow shown at the top of the page is computed by Snoflo as the sum of all monitored gauges along the river.
How is "percent of normal" calculated?
Today's aggregate streamflow is compared to the historical average aggregate streamflow on this calendar day across the river's full record. 100% means right on average; values above 100% indicate above-normal flow (wet year); values below indicate below-normal (dry year or drought).
Why are some gauges showing very different flows?
Gauges along a river measure flow at different points: headwater gauges read what's coming off the snowpack or mountain runoff; downstream gauges integrate everything upstream, including tributary inputs. Wide spreads usually mean a tributary is contributing significantly between gauges.
What's the elevation profile chart showing?
Each bubble is one gauge along the river, plotted by streamflow (x-axis) and elevation (y-axis), sized by gauge stage. Reading top-down traces the river from headwaters to mouth -- you can see flow build as elevation drops.
Can I get alerts when a specific gauge crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app on a per-gauge basis. Open any individual streamgauge from the table above and favorite it to set a discharge threshold.
