Aroostook River river
Total streamflow across the Aroostook River was last observed at 4,070 cfs, and is expected to yield approximately 8,073 acre-ft of water today; about 120% of normal. Average streamflow for this time of year is 3,401 cfs, with recent peaks last observed on 2018-04-28 when daily discharge volume was observed at 63,100 cfs.

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.

Aroostook River
The Aroostook River, located in Maine, is approximately 110 miles long and flows into the St. John River. The river has a rich history, being an important transportation route for Native Americans and later for lumber and agriculture industries. The hydrology of the river is influenced by the surrounding forests and wetlands, which play a critical role in regulating water flow and maintaining water quality. There are several dams and reservoirs along the river, including the Masardis Dam, which provides hydroelectric power and flood control. The river is also used for recreational activities such as fishing, kayaking, and camping. Additionally, the fertile soils along the river support agricultural production including potato farming. The Aroostook River is an important resource for both industry and recreation in the state of Maine.
Track the Aroostook 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 Aroostook River
Where does the data for the Aroostook 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.
