Total streamflow across the Westfield River was last observed at 793 cfs, and is expected to yield approximately 1,573 acre-ft of water today; about 58% of normal. River levels are low and may signify a drought. Average streamflow for this time of year is 1,363 cfs, with recent peaks last observed on 2011-08-29 when daily discharge volume was observed at 17,224 cfs.

Maximum discharge along the river is currently at the Westfield River Near Westfield reporting a streamflow rate of 565 cfs. This is also the highest stage along the Westfield River, with a gauge stage of 4.25 ft at this location. This river is monitored from 2 different streamgauging stations along the Westfield River, the highest being situated at an altitude of 464 ft, the Westfield River At Knightville.

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

Westfield River

The Westfield River is a 78-mile long river located in western Massachusetts. It is a tributary of the Connecticut River and has a rich history dating back to pre-colonial times. The river is fed by several small streams and tributaries, and its hydrology is influenced by numerous reservoirs and dams. Some of the most notable dams include Knightville Dam, Littleville Lake, and West Branch Reservoir. These reservoirs provide drinking water to nearby communities and also serve as recreational areas for fishing, boating, and swimming. The Westfield River is also an important resource for agriculture, providing irrigation water for fields and crops. Despite being impacted by pollution and development over the years, the river remains an important natural resource for the region.

FAQ

About the Westfield River

Where does the data for the Westfield 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.
