Squannacook River is a freestone river in Massachusetts.
Pick one of its USGS gauges and hear from us when the flow moves into or out of its usual range for the date, or crosses a flow you set. We check the public USGS reading every 2 hours and email only when it crosses, at most once every 6 hours. Flow alone is not a fishing forecast or a safety call.
Signed in: one step. Otherwise we email a confirmation link first. Every alert has one-click links to stop it.
Start from the agency's public access map. Nothing on this page grants or implies access: check the agency map, posted signs and landowner permission before you fish.

Seasons, limits, special regulations and closures for each reach are on the agency pages below. Read them before you go.
Each comes from the agency's own published list; where the list names a reach it is quoted. A designation applies to the listed reach, not necessarily the whole water. Listed in the finder under trout.

Measured from the NHDPlus High Resolution (flowlines and waterbodies) (U.S. Geological Survey, read 2026-11-04) for this water’s own mapped feature. Rounded figures; they describe the channel, not today’s conditions.
Areas the Protected Areas Database of the United States (PAD-US), public access (U.S. Geological Survey, Gap Analysis Project, read 2026-11-05) lists as owned or held in easement and open to the public, crossed by the mapped channel.

Normal for Nov 5: 25–92 ft³/s (middle half of 77 years of record). Now: 31.5 ft³/s, normal.
Normal for this date. 31.5 ft³/s is between the 25th and 75th percentiles of daily mean flow for Nov 5 at this gauge over 77 years of record (1950–2026): 10th 17, 25th 25, median 48, 75th 92, 90th 182 ft³/s.
Daily means on record for Nov 5: lowest 6.9 ft³/s, highest 873 ft³/s.
Classes as USGS labels them (hyswap: flow categories (WDFN_stats schema) (U.S. Geological Survey) ); percentiles from the USGS daily statistics (U.S. Geological Survey) (approved daily means; the reading is provisional and instantaneous).
Falling over 24 hours: discharge down 28.4%, from 44 to 31.5 ft³/s. Rising or falling means a change of more than 10% in discharge (or 0.2 ft of gauge height) over 24 hours; our rule of thumb, not a USGS class.
Below NWS action stage. The National Weather Service reports this gauge below its action stage. That is not a statement that wading is safe.
NWS observed 1.81 ft stage, 29 ft³/s at Nov 5, 5:00 PM EST (NWS gauge WGTM3; its stage datum can differ from the USGS gauge height).
NWS river forecast forecast issued Nov 5, 10:32 AM EST. Highest point: 2 ft, 42 ft³/s on Nov 7, 1:00 AM EST (Below NWS action stage).
