Mulberry River at Cass — common questions
3 questions
How fast can Mulberry River at Cass come up?
Fast. It is free-flowing, so rain upstream moves it directly. Several feet in a few hours is normal after a heavy storm.
Is Mulberry River at Cass high or low for this time of year?
The USGS median flow for late September here is 20 CFS, from 84 years of record (1938–2026). Today sits inside the middle half of those years, at 53% 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 07252000 every 15 to 60 minutes, and the National Weather Service reissues the flood forecast for MLBA4 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.
