What this means

The Guadalupe River near Bloomington is running below normal at 8.65 ft.

That puts it 2.12 ft below the median of 10.78 ft for mid-October, based on 26 years of readings. It is 11.35 ft below the flood stage of 20.00 ft. A year ago it stood at 7.20 ft (+1.45 ft).

It has dropped 0.10 ft over the past 24 hours. Without real rain upstream, that is unlikely to change quickly. In the last month it has stayed between 8.49 ft and 10.92 ft.

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

Flood stage here is 20.00 ft, 11.35 ft above the current reading. Beyond it, the National Weather Service also defines moderate and major flood stages.

What happens at each level

34.00 ft: This is the flood of record, which caused massive lowland flooding.
28.00 ft: Major flooding approaches the river levees near the San Antonio River confluence. Miles of Highway 35 and the flood plain near it flood, cutting off many homes and flooding a fishing camp near Tivoli. Hundreds of livestock are cut off and potentially drown.
27.50 ft: Major flooding occurs, isolating livestock. The river floods equipment and livestock in the flood plain and can flood residences downstream near Tivoli. Highway 35 east of Tivoli floods.
27.00 ft: Major flooding occurs. Flow downstream near Highway 35 is several hundred yards wide, cutting off many of the lowest homes. Livestock are cut off and could drown. Pumps, tank batteries, and any equipment in the flood plain below Victoria are flooded. The campground near Tivoli below Highway 35 and residences just above Highway 35 are flooded.
26.00 ft: Irrigation and oil well pumps, tank batteries, and equipment in the lower flood plain below Victoria flood. Livestock are cut off, may have to be fed by boat, and could drown. Homes downstream above Highway 35 on the left bank are cut off.
24.00 ft: Moderate lowland flooding occurs, with the river reaching well into the flood plain. Any oil tank batteries, pump jacks, and secondary roads near the river may be flooded.
20.00 ft: Minor lowland flooding occurs, with the flow reaching the right flood plain near the Invista Plant near Bloomington. Downstream above Highway 35, the flow escapes into the left flood plain cutting off the lowest homes.
