North Fork Red River at Altus Dam — common questions
3 questions
How do releases from Lake Altus-Lugert affect this stretch?
Directly and fast. When the dam generates, flow here can climb by an order of magnitude within the hour, with no rain anywhere in the basin. That sudden release is the real hazard on a tailwater. The pool level is on lakelvl.com, linked below.
Is North Fork Red River at Altus Dam high or low for this time of year?
The USGS median flow for late September here is 0.2 CFS, from 48 years of record (1978–2026). Today sits inside the middle half of those years, at 76% 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 07303000 every 15 to 60 minutes, and the National Weather Service reissues the flood forecast for LGTO2 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.
