What this means

Lightning Creek at Clark Fork is running at a record low at 7.84 ft.

No reading on record has been lower: the old record low was 8.00 ft, from September 14, 2001.

It has dropped 0.05 ft over the past 24 hours. Without real rain upstream, that is unlikely to change quickly. In the last month it has stayed between 7.84 ft and 7.93 ft.

Fall is often low-water season on rivers, and it usually takes a few days of steady rain to change that.
