The Colmesneil plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
7.30 inches of rain fell in two days, the most for this week of the year since records began in 1953. The next wettest, 5.21 inches, fell in 1998.
Colmesneil’s center stands about 290 ft above sea level. Within three miles the land runs from 180 ft to 410 ft, a difference of 230 ft: rolling country.
The section below crosses 3 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 53×. 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, sandstone. Age: Miocene, 5.3 to 23 million years old. About 13 mi of the line.
Coarse-detrital, fine-detrital. Age: Pliocene, 2.6 to 5.3 million years old. About 10 mi of the line.
Fine-detrital, coarse-detrital. Age: Holocene, less than 12,000 years old. About 0.9 mi of the line.

A raindrop that lands in Colmesneil reaches the Gulf of America by way of Wolf Creek and the Neches: about 160 river miles.
Lakes on the way: Sabine Lake and B A Steinhagen Lake.
110 miles of the trip are on the Neches.

Colmesneil has a humid subtropical climate. Summer afternoons average 92° in August; winter nights fall to about 38° in January. About 59 inches of rain fall in a normal year.
On November 14 Colmesneil normally reaches 69° and falls to 48°. The record high is 85°, in 1955; the record low 26°, in 2019. The most rain on this date, 2.28 in, fell in 1998.
