Map of USGS gauge 06477500 and the river around it
Where FIRESTEEL CREEK NEAR MOUNT VERNON, SD sits.
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: 0.03–1.2 ft³/s (middle half of 71 years of record). Now: 3.23 ft³/s, above normal.
Above normal for this date. 3.23 ft³/s is between the 75th and 90th percentiles of daily mean flow for Nov 5 at this gauge over 71 years of record (1956–2026): 10th 0, 25th 0.03, median 0.2, 75th 1.2, 90th 8.7 ft³/s.
Daily means on record for Nov 5: lowest 0 ft³/s, highest 82.2 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).
Falling over 24 hours: discharge down 18.8%, from 3.98 to 3.23 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)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.
