Water level

What this means

Low water at Big River below Bonne Terre: the gauge reads 2.57 ft, far below normal for mid-October.

The level has held steady over the past 24 hours. Without real rain upstream, that is unlikely to change quickly. The 30-day range is 2.52 ft – 2.60 ft.

Fall is often low-water season on rivers, and it usually takes a few days of steady rain to change that. The sensor also reports a water temperature of 58 °F.

Compared with 5 years of daily readings for this time of year. How to read levels

Paddling and fishing conditions

At low levels, plan for shorter paddling trips and expect to walk your boat through a few shoals.
