Map of USGS gauge 06483950 and the river around it
Where BIG SIOUX RIVER NEAR HAWARDEN, 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. South Dakota Game, Fish and Parks publishes no water-temperature line for trout anglers that we found. The lines below are the National Park Service's, federal guidance, not a South Dakota rule: 68°F.
Species list not on file for this gauge. Check the South Dakota Game, Fish and Parks: South Dakota fishery surveys, reports and stocking.
Normal for Nov 5: 431–2,350 ft³/s (middle half of 11 years of record). Now: 2,590 ft³/s, above normal.
Above normal for this date. 2,590 ft³/s is between the 75th and 90th percentiles of daily mean flow for Nov 5 at this gauge over 11 years of record (2016–2026): 10th 269, 25th 431, median 963, 75th 2,350, 90th 5,190 ft³/s.
Daily means on record for Nov 5: lowest 265 ft³/s, highest 5,210 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 (+5.3% 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)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.
Below NWS action stage. The National Weather Service reports this gauge below its action stage. That is not a statement that wading is safe.
NWS observed 14.7 ft stage, 2,410 ft³/s at Nov 5, 9:30 PM CST (NWS gauge HWDI4; 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.
