What this means

At 2.70 ft, the W Fk Trinity River at Grand Prairie is below normal for mid-October.

The median for mid-October is 3.36 ft, based on 38 years of readings, so the river stage is 0.65 ft below typical. It is 24.30 ft below the flood stage of 27.00 ft. On the same day last year the reading was 2.50 ft, a difference of +0.20 ft.

The level is falling, down 0.08 ft over the past 24 hours. Without real rain upstream, that is unlikely to change quickly.

Fall is often low-water season on rivers, and it usually takes a few days of steady rain to change that. The water temperature at the gauge is 73 °F.

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.

The National Weather Service puts flood stage for this gauge at 27.00 ft, still 24.30 ft away.
