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 09379500 and the river around it
Where SAN JUAN RIVER NEAR BLUFF, UT 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. Utah Division of Wildlife Resources publishes no water-temperature line for trout anglers that we found. The lines below are the National Park Service's, federal guidance, not a Utah rule: 68°F.
This gauge is on the same river as our page for San Juan River, but no agency page we read lists its species.
Normal for Nov 5: 734–1,370 ft³/s (middle half of 101 years of record). Now: 25,000 ft³/s, highest for this date on record.
Highest for this date on record for this date. 25,000 ft³/s is above the highest daily mean recorded on this date of daily mean flow for Nov 5 at this gauge over 101 years of record (1915–2026): 10th 616, 25th 734, median 897, 75th 1,370, 90th 2,140 ft³/s.
Daily means on record for Nov 5: lowest 285 ft³/s, highest 6,070 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).
Rising over 24 hours: discharge up 14.2%, from 21,900 to 25,000 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)Rising water. Rising over the last 24 hours (discharge up 14.2%). Keep your way back to the bank in sight and watch the level while you fish. “Rising” is our rule of thumb: more than 10% in discharge or 0.2 ft of gauge height in 24 hours, not a USGS or NWS class.
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.

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.
Below NWS action stage. The National Weather Service reports this gauge below its action stage. That is not a statement that wading is safe.
NWS observed 20.6 ft stage, 25,600 ft³/s at Nov 5, 7:30 PM MST (NWS gauge BFFU1; its stage datum can differ from the USGS gauge height).
NWS river forecast forecast issued Nov 5, 10:04 AM MST. Highest point: 22.4 ft, 30,300 ft³/s on Nov 5, 11:00 AM MST (Below NWS action stage).
