3.48 inches of rain fell in two days, the most for this week of the year since records began in 1894. The next wettest, 3.15 inches, fell in 1899.
Dibble’s center stands about 1,240 ft above sea level. Within three miles the land runs from 1,120 ft to 1,340 ft, a difference of 220 ft: rolling country.
Under the town center the state geologic map shows Terrace Deposits (coarse-detrital, fine-detrital), from the Pleistocene, less than 2.6 million years old.
The section below crosses 5 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 58×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sandstone, conglomerate. Age: Permian, 252 to 299 million years old. About 11 mi of the line.
Conglomerate, shale, siltstone. Age: Permian, 252 to 299 million years old. About 10 mi of the line.
Shale, sandstone, siltstone. Age: Permian, 252 to 299 million years old. About 3 mi of the line.
Coarse-detrital, fine-detrital. Age: Pleistocene, less than 2.6 million years old. About 0.8 mi of the line.
Fine-detrital. Age: Holocene, less than 12,000 years old. About 0.5 mi of the line.

A raindrop that lands in Dibble reaches the Gulf of America by way of Criner Creek, the Washita, the Red River, the Atchafalaya and the Lower Atchafalaya: about 1,000 river miles.
680 miles of the trip are on the Red River.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Dibble; river miles along the main stem, rounded.
Dibble has a humid subtropical climate. Summer afternoons average 93° in July; winter nights fall to about 28° in January. About 38 inches of rain fall in a normal year, with about 4 inches of snow.
On November 14 Dibble normally reaches 62° and falls to 39°. The record high is 81°, in 2025; the record low 13°, in 1916. The most rain on this date, 1.36 in, fell in 1928.
