What this means

The Llano River at Llano is well above normal at 3.12 ft.

The median for mid-October is 1.55 ft, based on 29 years of readings, so the river stage is 1.57 ft above typical. It is 6.88 ft below the flood stage of 10.00 ft. On the same day last year the reading was 0.74 ft, a difference of +2.38 ft.

It has risen 0.86 ft over the past 24 hours. If the rise continues, low-lying paths and riverside parking can go under water. In the last month it has stayed between 1.51 ft and 8.05 ft.

That stands out in fall, when many rivers are usually near their lowest.

Flood levels and safety

Most flood deaths in the US happen in vehicles. Six inches of fast water can knock an adult off their feet, and a foot or two can float a car. If a road is covered, turn around.

Readings can change quickly after heavy rain upstream, so check again before heading near the water.
