Map of USGS gauge 03451000 and the river around it
Where SWANNANOA RIVER AT BILTMORE, NC sits.
No current water-temperature reading at this gauge, so no temperature guidance is given. Take a stream thermometer. NC Wildlife Resources Commission publishes no water-temperature line for trout anglers that we found. The lines below are the National Park Service's, federal guidance, not a North Carolina rule, with N.C. Cooperative Extension's own figure added: 68°F and 70°F.
Species list not on file for this gauge. Check the North Carolina Wildlife Resources Commission: North Carolina daily trout stockings · North Carolina fishing regulations.
Normal for Nov 5: 43–120 ft³/s (middle half of 98 years of record). Now: 84.9 ft³/s, normal.
Normal for this date. 84.9 ft³/s is between the 25th and 75th percentiles of daily mean flow for Nov 5 at this gauge over 98 years of record (1921–2026): 10th 33, 25th 43, median 70, 75th 120, 90th 289 ft³/s.
Daily means on record for Nov 5: lowest 18 ft³/s, highest 468 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).
Falling over 24 hours: discharge down 57.5%, from 200 to 84.9 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.
Below NWS action stage. The National Weather Service reports this gauge below its action stage. That is not a statement that wading is safe.
