Map of USGS gauge 04265432 and the river around it
Where GRASS RIVER AT CHASE MILLS NY sits.
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.
Species list not on file for this gauge. Check the New York State Department of Environmental Conservation: New York fish stocking lists · New York freshwater fishing regulations.
Normal for Nov 5: 550–1,700 ft³/s (middle half of 23 years of record). Now: 279 ft³/s, lowest for this date on record.
Lowest for this date on record for this date. 279 ft³/s is below the lowest daily mean recorded on this date of daily mean flow for Nov 5 at this gauge over 23 years of record (2004–2026): 10th 477, 25th 550, median 903, 75th 1,700, 90th 2,440 ft³/s.
Daily means on record for Nov 5: lowest 299 ft³/s, highest 3,990 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 (+3.3% 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.
