Map of USGS gauge 04227500 and the river around it
Where GENESEE RIVER NEAR MOUNT MORRIS NY sits, with 4 other gauges 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 New York DEC uses are 70°F.
Normal for Nov 5: 342–1,850 ft³/s (middle half of 75 years of record). Now: 467 ft³/s, normal.
Normal for this date. 467 ft³/s is between the 25th and 75th percentiles of daily mean flow for Nov 5 at this gauge over 75 years of record (1952–2026): 10th 218, 25th 342, median 825, 75th 1,850, 90th 4,030 ft³/s.
Daily means on record for Nov 5: lowest 132 ft³/s, highest 6,740 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 (−7.7% 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.
Species the agency lists for Genesee River: Brown Trout, Chinook Salmon, Coho Salmon, Rainbow Trout, Steelhead.
