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
General guidance from the readings and the published lines named above, not a fishing forecast. Local rules and closures come first.

Map of USGS gauge 09371010 and the river around it
Where SAN JUAN RIVER AT FOUR CORNERS, CO sits, with 1 other gauge 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 Colorado Parks and Wildlife uses are 71°F.
This gauge is on our page for San Juan River, but no agency page we read lists its species.
Normal for Nov 5: 770–1,190 ft³/s (middle half of 48 years of record). Now: 7,690 ft³/s, highest for this date on record.
Highest for this date on record for this date. 7,690 ft³/s is above the highest daily mean recorded on this date of daily mean flow for Nov 5 at this gauge over 48 years of record (1978–2026): 10th 627, 25th 770, median 919, 75th 1,190, 90th 1,450 ft³/s.
Daily means on record for Nov 5: lowest 500 ft³/s, highest 5,400 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 58.2%, from 18,400 to 7,690 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.
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.
