Map of USGS gauge 01197000 and the river around it
Where EAST BRANCH HOUSATONIC RIVER AT COLTSVILLE, MA sits and our water's map point.
No current water-temperature reading at this gauge, so no temperature guidance is given. Take a stream thermometer. MassWildlife publishes no water-temperature line for trout anglers that we found. The lines below are the National Park Service's, federal guidance, not a Massachusetts rule: 68°F.
This gauge is on our page for East Branch Housatonic River, but no agency page we read lists its species.
Normal for Nov 5: 41–109 ft³/s (middle half of 90 years of record). Now: 53.1 ft³/s, normal.
Normal for this date. 53.1 ft³/s is between the 25th and 75th percentiles of daily mean flow for Nov 5 at this gauge over 90 years of record (1937–2026): 10th 27, 25th 41, median 69, 75th 109, 90th 158 ft³/s.
Daily means on record for Nov 5: lowest 12 ft³/s, highest 690 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).
Steady over 24 hours (+9.5% discharge). 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.
Flood categories: action stage, minor, moderate and major flooding (National Weather Service)Turn Around Don't Drown. “A mere 6 inches of fast-moving flood water can knock over an adult.” No flow number makes a crossing safe; if in doubt, stay out.

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 0.91 ft stage, 54 ft³/s at Nov 5, 9:30 PM EST (NWS gauge CTVM3; its stage datum can differ from the USGS gauge height).
Forecasts are issued as needed during times of high water, but are not routinely available.
