Map of USGS gauge 06821150 and the river around it
Where Little Platte River at Smithville, MO sits, with 1 other gauge on the same river.
No current water-temperature reading at this gauge, so no temperature guidance is given. Take a stream thermometer. Missouri Department of Conservation publishes no water-temperature line for trout anglers that we found. The lines below are the National Park Service's, federal guidance, not a Missouri rule, with Missouri Department of Conservation's own figure added: 68°F and 70°F.

Normal for Nov 5: 10–20 ft³/s (middle half of 50 years of record). Now: 21 ft³/s, above normal.
Above normal for this date. 21 ft³/s is between the 75th and 90th percentiles of daily mean flow for Nov 5 at this gauge over 50 years of record (1977–2026): 10th 5.9, 25th 10, median 12, 75th 20, 90th 490 ft³/s.
Daily means on record for Nov 5: lowest 0.95 ft³/s, highest 1,370 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 37.1%, from 33.4 to 21 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.
