Total streamflow across the Still River was last observed at 104 cfs, and is expected to yield approximately 206 acre-ft of water today; about 50% of normal. River levels are low and may signify a drought. Average streamflow for this time of year is 209 cfs, with recent peaks last observed on 2021-09-02 when daily discharge volume was observed at 5,110 cfs.

Maximum discharge along the river is currently at the Still River At Route 7 At Brookfield Center reporting a streamflow rate of 54.4 cfs. This is also the highest stage along the Still River, with a gauge stage of 6.69 ft at this location. This river is monitored from 2 different streamgauging stations along the Still River, the highest being situated at an altitude of 519 ft, the Still River At Robertsville.

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

Still River

The Still River is a 25-mile-long river located in western Massachusetts that flows into the Housatonic River. The river has a rich history, having played a vital role in the industrialization of the region during the 19th century. Today, the Still River is used for recreational purposes such as fishing, canoeing, and kayaking. There are several dams and reservoirs along the river, including the Wachusett Reservoir, which is the largest reservoir in Massachusetts and provides drinking water to millions of people in the Boston area. The river also provides water for agricultural purposes, including irrigation for local farms. Despite its relatively short length, the Still River is an important resource for the people and communities it serves.

FAQ

About the Still River

Where does the data for the Still 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.
