Map of USGS gauge 09402500 and the river around it
Where COLORADO RIVER NEAR GRAND CANYON, AZ 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 Arizona Game and Fish uses are 67°F.
This gauge is on our page for Colorado River, but no agency page we read lists its species.
Normal for Nov 5: 6,940–12,000 ft³/s (middle half of 102 years of record). Now: 12,500 ft³/s, above normal.
Above normal for this date. 12,500 ft³/s is between the 75th and 90th percentiles of daily mean flow for Nov 5 at this gauge over 102 years of record (1923–2026): 10th 5,300, 25th 6,940, median 9,040, 75th 12,000, 90th 16,400 ft³/s.
Daily means on record for Nov 5: lowest 1,270 ft³/s, highest 36,400 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).
Steady over 24 hours (−1.6% 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.
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.
NWS observed 16.7 ft stage, 12,500 ft³/s at Nov 5, 5:15 PM MST (NWS gauge CGCA3; its stage datum can differ from the USGS gauge height).
NWS has not set flood categories for this gauge.
NWS river forecast forecast issued Nov 5, 9:47 AM MST. Highest point: 17.3 ft, 14,500 ft³/s on Nov 8, 11:00 AM MST.
