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 05458000 and the river around it
Where Little Cedar River near Ionia, 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.
Species list not on file for this gauge. Check the Iowa Department of Natural Resources: Iowa fishing regulations and laws.
Normal for Nov 5: 38–154 ft³/s (middle half of 72 years of record). Now: 593 ft³/s, much above normal.
Much above normal for this date. 593 ft³/s is above the 90th percentile of daily mean flow for Nov 5 at this gauge over 72 years of record (1955–2026): 10th 23, 25th 38, median 69, 75th 154, 90th 379 ft³/s.
Daily means on record for Nov 5: lowest 12 ft³/s, highest 641 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 (+4.8% 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 far above normal. Above the 90th percentile of daily mean flow for this date (USGS class “much above normal”), from 72 years of record. Expect higher, faster water than usual for the season.
