Map of USGS gauge 05464000 and the river around it
Where Cedar River at Waterloo, IA sits, with 4 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: 956–2,600 ft³/s (middle half of 86 years of record). Now: 10,800 ft³/s, much above normal.
Much above normal for this date. 10,800 ft³/s is above the 90th percentile of daily mean flow for Nov 5 at this gauge over 86 years of record (1941–2026): 10th 561, 25th 956, median 1,660, 75th 2,600, 90th 5,590 ft³/s.
Daily means on record for Nov 5: lowest 403 ft³/s, highest 12,100 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 21.5%, from 8,890 to 10,800 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.
Species list not on file for this gauge. Check the Iowa Department of Natural Resources: Iowa fishing regulations and laws.
Above NWS action stage. Above action stage: high, fast water. Don't wade.
Flood categories: action stage, minor, moderate and major flooding (National Weather Service)NWS forecast: Above NWS action stage. The National Weather Service river forecast for this gauge reaches that category. Plan around it and check the forecast again before you go.
Flood categories: action stage, minor, moderate and major flooding (National Weather Service)Rising water. Rising over the last 24 hours (discharge up 21.5%). 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 86 years of record. Expect higher, faster water than usual for the season.
hyswap: flow categories (WDFN_stats schema) (U.S. Geological Survey) Statistics documentation (percentiles of daily mean discharge) (U.S. Geological Survey)Turn Around Don't Drown. “A mere 6 inches of fast-moving flood water can knock over an adult.” No flow number makes a crossing safe; if in doubt, stay out.
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.
Above NWS action stage. Above action stage: high, fast water. Don't wade.
NWS observed 8.59 ft stage, 10,800 ft³/s at Nov 5, 9:00 PM CST (NWS gauge ALOI4; its stage datum can differ from the USGS gauge height).
NWS river forecast forecast issued Nov 5, 8:06 PM CST. Highest point: 8.9 ft, 12,000 ft³/s on Nov 6, 12:00 PM CST (Above NWS action stage).
