4.23 inches of rain fell in two days, the most for this week of the year since records began in 1893. The next wettest, 3.14 inches, fell in 1978.
Campbell’s center stands about 600 ft above sea level. Within three miles the land runs from 510 ft to 620 ft, a difference of 110 ft: gently rolling country.
Under the town center the state geologic map shows Navarro Group, undivided (clay, sand), from the Late Cretaceous, 66 to 72 million years old.
The section below crosses 4 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 64×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Clay, sand. Age: Late Cretaceous, 66 to 72 million years old. About 12 mi of the line.
Sand. Age: Pleistocene to Holocene, less than 2.6 million years old. About 6 mi of the line.
Fine-detrital, coarse-detrital. Age: Holocene, less than 12,000 years old. About 4 mi of the line.
Claystone. Age: Late Cretaceous, 66 to 72 million years old. About 2 mi of the line.

A raindrop that lands in Campbell reaches the Gulf of America by way of Timber Creek, the Cowleech Fork Sabine and the Sabine: about 500 river miles.
Lakes on the way: Toledo Bend Reservoir, Sabine Lake and Lake Tawakoni.
240 miles of the trip are on the Sabine.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Campbell; river miles along the main stem, rounded.
Campbell has a humid subtropical climate. Summer afternoons average 95° in August; winter nights fall to about 34° in January. About 46 inches of rain fall in a normal year.
On November 14 Campbell normally reaches 67° and falls to 44°. The record high is 87°, in 2005; the record low 22°, in 1986. The most rain on this date, 1.82 in, fell in 1970.
Normals 1991–2020 and records since 1893 at Sulphur Springs, 19 miles east, 100 ft lower. NOAA, through RCC-ACIS.
