Total streamflow across the Deerfield River was last observed at 581 cfs, and is expected to yield approximately 1,152 acre-ft of water today; about 31% of normal. River levels are low and may signify a drought. Average streamflow for this time of year is 1,902 cfs, with recent peaks last observed on 2011-09-08 when daily discharge volume was observed at 28,100 cfs.

Maximum discharge along the river is currently at the Deerfield River Near West Deerfield reporting a streamflow rate of 358 cfs. This is also the highest stage along the Deerfield River, with a gauge stage of 2.22 ft at this location. This river is monitored from 2 different streamgauging stations along the Deerfield River, the highest being situated at an altitude of 517 ft, the Deerfield River At Charlemont.

Profile

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.

About this river

Deerfield River

The Deerfield River is a major river in Massachusetts that is 76 miles long and is a tributary of the Connecticut River. The river has a rich history and was used for transportation and power generation in the 19th and 20th centuries. The river includes several reservoirs and dams, including the Fife Brook Dam, Bear Swamp Power Station, and Harriman Reservoir. These dams and reservoirs provide hydroelectric power to the surrounding areas, but also impact the river’s natural flow and ecology. The Deerfield River is popular for recreational activities such as fishing, kayaking, and rafting. The river is also used for agriculture, with many farms located along its banks. The river’s natural beauty and cultural significance make it an important resource for the local community.

FAQ

About the Deerfield River

Where does the data for the Deerfield 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.
