Map of USGS gauge 01172010 and the river around it
Where CONNECTICUT R AT I-391 BRIDGE AT HOLYOKE, MA sits, with 3 other gauges on the same river.
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.
Normal for Nov 5: 7,090–20,400 ft³/s (middle half of 24 years of record). Now: 4,170 ft³/s, lowest for this date on record.
Lowest for this date on record for this date. 4,170 ft³/s is below the lowest daily mean recorded on this date of daily mean flow for Nov 5 at this gauge over 24 years of record (2003–2026): 10th 4,890, 25th 7,090, median 12,700, 75th 20,400, 90th 29,000 ft³/s.
Daily means on record for Nov 5: lowest 4,540 ft³/s, highest 59,400 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).
Rising over 24 hours: discharge up 17.8%, from 3,540 to 4,170 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.
Species list not on file for this gauge. Check the Massachusetts Division of Marine Fisheries / MassWildlife: Massachusetts trout stocking report · Massachusetts recreational saltwater fishing regulations.
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)Rising water. Rising over the last 24 hours (discharge up 17.8%). Keep your way back to the bank in sight and watch the level while you fish. “Rising” is our rule of thumb: more than 10% in discharge or 0.2 ft of gauge height in 24 hours, not a USGS or NWS class.
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.
