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 05463500 and the river around it
Where Black Hawk Creek at Hudson, IA sits.
No current water-temperature reading at this gauge, so no temperature guidance is given. Take a stream thermometer. Iowa DNR publishes no water-temperature line for trout anglers that we found. The lines below are the National Park Service's, federal guidance, not a Iowa rule, with Iowa DNR's own figure added: 68°F and 75°F.

Normal for Nov 5: 31.8–155 ft³/s (middle half of 68 years of record). Now: 1,390 ft³/s, highest for this date on record.
Highest for this date on record for this date. 1,390 ft³/s is above the highest daily mean recorded on this date of daily mean flow for Nov 5 at this gauge over 68 years of record: 10th 14.9, 25th 31.8, median 87, 75th 155, 90th 327 ft³/s.
Daily means on record for Nov 5: lowest 9.3 ft³/s, highest 1,020 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 (+7.8% 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.
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.
