Map of USGS gauge 01066000 and the river around it
Where Saco River at Cornish, Maine 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: the trout lines Maine IF&W uses are 68°F.
This gauge is on the same river as our page for Saco River, but no agency page we read lists its species.
Normal for Nov 5: 1,110–3,350 ft³/s (middle half of 110 years of record). Now: 766 ft³/s, below normal.
Below normal for this date. 766 ft³/s is between the 10th and 25th percentiles of daily mean flow for Nov 5 at this gauge over 110 years of record (1917–2026): 10th 714, 25th 1,110, median 1,730, 75th 3,350, 90th 5,500 ft³/s.
Daily means on record for Nov 5: lowest 344 ft³/s, highest 10,100 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 (−2.2% 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 2.34 ft stage, 761 ft³/s at Nov 5, 6:45 PM EST (NWS gauge CNHM1; 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.
