Map of USGS gauge 06482020 and the river around it
Where BIG SIOUX R AT NORTH CLIFF AVE AT SIOUX FALLS, SD sits, with 3 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.
Normal for Nov 5: 76–469 ft³/s (middle half of 55 years of record). Now: 776 ft³/s, above normal.
Above normal for this date. 776 ft³/s is between the 75th and 90th percentiles of daily mean flow for Nov 5 at this gauge over 55 years of record (1972–2026): 10th 39, 25th 76, median 234, 75th 469, 90th 957 ft³/s.
Daily means on record for Nov 5: lowest 18 ft³/s, highest 2,930 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 13%, from 687 to 776 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 South Dakota Game, Fish and Parks: South Dakota fishery surveys, reports and stocking · South Dakota regulations and handbooks.
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 13%). 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.
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.
