Map of USGS gauge 01333000 and the river around it
Where GREEN RIVER AT WILLIAMSTOWN, MA sits, with 1 other gauge on the same river 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 the same river as our page for Green River, but no agency page we read lists its species.
Normal for Nov 5: 27–99 ft³/s (middle half of 77 years of record). Now: 35.1 ft³/s, normal.
Normal for this date. 35.1 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 11, 25th 27, median 53, 75th 99, 90th 132 ft³/s.
Daily means on record for Nov 5: lowest 5.3 ft³/s, highest 223 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 61.8%, from 21.7 to 35.1 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.
Rising water. Rising over the last 24 hours (discharge up 61.8%). 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.
Turn Around Don't Drown (National Weather Service)Guidance from the readings above and the published thresholds named with each line; not a fishing forecast, a safety guarantee or a statement about access. Local rules and closures come first.
The National Weather Service has no flood-stage gauge here, so no official flood category is shown.
Checked Nov 5, 11:00 PM EST; readings refresh at most every 15 minutes and statistics daily. Provisional USGS data can be revised. Conditions change: re-check before you go. This is general guidance, not a fishing forecast, a safety guarantee or a statement about access.
