Map of USGS gauge 06918740 and the river around it
Where Little Sac River near Morrisville, MO sits.
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: 22–177 ft³/s (middle half of 58 years of record). Now: 17.4 ft³/s, below normal.
Below normal for this date. 17.4 ft³/s is between the 10th and 25th percentiles of daily mean flow for Nov 5 at this gauge over 58 years of record (1969–2026): 10th 16, 25th 22, median 53, 75th 177, 90th 528 ft³/s.
Daily means on record for Nov 5: lowest 8.2 ft³/s, highest 3,570 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 (−7.4% 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.
