Water level

What this means

At 5.99 ft, the Tuolumne River below Lagrange Dam near Lagrange is below normal for mid-October.

The level is falling, down 1.00 ft over the past 24 hours. Without real rain upstream, that is unlikely to change quickly. Over the past 30 days it has moved between 5.98 ft and 9.09 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 53 °F.

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

What the stage means on the water

Low water means more dragging on shallow riffles and slower floats. Fish crowd into the deeper runs, and warm, low water stresses them, so play and release them quickly.

Questions and answers

Is gage height the same as water depth?

No. Gage height is measured from a fixed reference point chosen by the agency, so a reading of 10 ft does not mean the river is 10 ft deep.

What is the water level of Tuolumne River below Lagrange Dam near Lagrange today?

On Oct 20, 2026, 10:15 AM PDT, the water level was 5.99 ft. Down 1.00 ft over the last 24 hours.

Is Tuolumne River below Lagrange Dam near Lagrange rising or falling?

Down 1.00 ft over the last 24 hours.

Is the level of Tuolumne River below Lagrange Dam near Lagrange normal?

Low for mid-October. Compared with 5 years of daily readings for this time of year.

How we check values

Each reading is stored as published. We hold back values that jump faster than physically plausible and show the measurement time with every value.
