Map of USGS gauge 06471500 and the river around it
Where ELM RIVER AT WESTPORT, SD 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: 3.2–8.44 ft³/s (middle half of 81 years of record). Now: 16.7 ft³/s, above normal.
Above normal for this date. 16.7 ft³/s is between the 75th and 90th percentiles of daily mean flow for Nov 5 at this gauge over 81 years of record: 10th 1.3, 25th 3.2, median 5.71, 75th 8.44, 90th 17.4 ft³/s.
Daily means on record for Nov 5: lowest 0.1 ft³/s, highest 283 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 (+0% 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.

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 4.37 ft stage, 25 ft³/s at Nov 5, 9:00 PM CST (NWS gauge WESS2; 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.
