About Niangua River at Windyville
The NWS impact statements attached to this forecast point are unusual. The lowest one is set at 4 feet and reads, in the NWS's own words, that river conditions may be difficult for some non motorized vessels. Most gauges on this site carry nothing below action stage, and what they carry is about property rather than boats.
The crest record contains an oddity worth noticing. On 25 September 1993 the river peaked at 44,700 CFS and crested at 24.36 feet. On 27 December 2015 it peaked at 58,800 CFS, 14,000 CFS more, and crested at 24.35 feet, a hundredth of a foot lower. The published statistics cover 1991 to 2026 and put the September and October medians at 48 CFS against 362 in May.
Niangua River at Windyville — common questions
6 questions
What do the NWS categories mean on this gauge?
Action stage is 10 feet, which the NWS pairs with 5,473 CFS; minor flood is 12 feet and 7,993 CFS; moderate is 20 feet and 25,225 CFS. This is one of the few forecast points on this site that publishes a flow alongside each stage, which makes it possible to read the discharge figure on this page directly against the ladder.
How low does this river get in late summer?
Low. The published medians for September and October are both 48 CFS, and August is 50, against 362 in May and 350 in April. That is a seven to one seasonal swing on a 377 square mile drainage. The record low daily mean is 10 CFS, on 16 August 2007.
Does the Pomme de Terre gauge track this one?
Moderately. Over 9,196 shared days since 1991 the correlation is 0.656 and this gauge runs at a median of about 0.7 times the Pomme de Terre at Hermitage, 26.9 miles away. The same Ozark storm systems cross both, but the Pomme de Terre reading is shaped by its reservoir and this one is not, which is where the looseness comes from.
Does rain upstream change Niangua River at Windyville quickly?
Yes. It is free-flowing, so rain upstream moves it directly. Several feet in a few hours is normal after a heavy storm.
Is Niangua River at Windyville high or low for this time of year?
The USGS median flow for late September here is 47 CFS, from 25 years of record (1991–2026). Today sits in the lowest 5% of those years, at 37% of the median. The comparison is what makes the raw number mean anything: the same reading is a drought on one river and a flood on another.
How often does this reading update?
USGS transmits from gauge 06923250 every 15 to 60 minutes, and the National Weather Service reissues the flood forecast for WNYM7 a few times a day — more often when the river is rising. This page refreshes from both when you open it. The timestamp is in the gauge's local time.
