Still River Flow
As of 2026-08-17, the Still River is flowing at a combined 150 cfs across 2 USGS streamgauges — 139% of normal for this time of year, versus a seasonal average of 108 cfs.
Total streamflow across the Still River was last observed at 150 cfs, and is expected to yield approximately 298 acre-ft of water today; about 139% of normal. River levels are high. Average streamflow for this time of year is 108 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 133 cfs. This is also the highest stage along the Still River, with a gauge stage of 7.63 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.

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.

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.

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 Still River
How is the Still River flowing right now?
As of 2026-08-17, the Still River is flowing at a combined 150 cfs across its USGS streamgauges, about 139% of normal for this date. The live per-gauge breakdown and 24-hour trend are shown above.
Is the Still River running high or low right now?
Check the percent-of-normal figure on this page: above 100% means the river is running higher than its seasonal average for the date, below 100% means lower. The per-gauge table shows which reaches are highest and lowest.
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.
