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 05388250 and the river around it
Where Upper Iowa River near Dorchester, IA sits, with 2 other gauges on the same river.
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: 209–519 ft³/s (middle half of 52 years of record). Now: 1,140 ft³/s, much above normal.
Much above normal for this date. 1,140 ft³/s is above the 90th percentile of daily mean flow for Nov 5 at this gauge over 52 years of record (1939–2026): 10th 164, 25th 209, median 338, 75th 519, 90th 970 ft³/s.
Daily means on record for Nov 5: lowest 134 ft³/s, highest 1,650 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 19.7%, from 952 to 1,140 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 19.7%). 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 far above normal. Above the 90th percentile of daily mean flow for this date (USGS class “much above normal”), from 52 years of record. Expect higher, faster water than usual for the season.

NWS observed 8.29 ft stage, 1,220 ft³/s at Nov 5, 7:00 PM CST (NWS gauge DCHI4; its stage datum can differ from the USGS gauge height).
Forecasts are issued as needed during times of high water, but are not routinely available.
