What the agencies suggest
During periods of high water, fish move towards the banks to find calmer water and lower velocitiesPennsylvania Fish and Boat Commission
Wading and boating should be avoided if waters are running high and muddy and the streambed is not visiblePennsylvania Fish and Boat Commission
If stream conditions are not favorable, consider fishing at a lakePennsylvania Fish and Boat Commission

Map of USGS gauge 02231291 and the river around it
Where NASSAU RIVER NEAR TISONIA, FL sits and our water's map point.
No current water-temperature reading at this gauge, so no temperature guidance is given. Take a stream thermometer. Florida Fish and Wildlife Conservation 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 Florida rule: 68°F.
This gauge is on our page for Nassau River, but no agency page we read lists its species.
Normal for Nov 5: -903–144 ft³/s (middle half of 13 years of record). Now: 18,100 ft³/s, highest for this date on record.
Highest for this date on record for this date. 18,100 ft³/s is above the highest daily mean recorded on this date of daily mean flow for Nov 5 at this gauge over 13 years of record (2014–2026): 10th -2,620, 25th -903, median -296, 75th 144, 90th 910 ft³/s.
Daily means on record for Nov 5: lowest -3,540 ft³/s, highest 1,060 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 12.1%, from 20,600 to 18,100 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.
Flood categories: action stage, minor, moderate and major flooding (National Weather Service)Flow above the record for this date. Higher than any daily mean USGS has recorded on this date at this gauge. Expect much higher, faster water than usual for the season.
