The Jewett 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.
3.91 inches of rain fell in two days, the most for this week of the year since records began in 1937. The next wettest, 2.94 inches, fell in 1987.
Jewett’s center stands about 500 ft above sea level. Within three miles the land runs from 370 ft to 540 ft, a difference of 170 ft: gently rolling country.
Under the town center the state geologic map shows Queen City Sand (siltstone, sandstone), from the Middle Eocene, 38 to 48 million years old.
The section below crosses 7 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.

A raindrop that lands in Jewett reaches the Gulf of America by way of Yellow Branch, Brushy Creek, the Navasota and the Brazos: about 350 river miles.
230 miles of the trip are on the Brazos.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Jewett; river miles along the main stem, rounded.
Jewett has a humid subtropical climate. Summer afternoons average 95° in August; winter nights fall to about 35° in January. About 42 inches of rain fall in a normal year.
On November 14 Jewett normally reaches 70° and falls to 44°. The record high is 88°, in 1955; the record low 21°, in 2019. The most rain on this date, 0.45 in, fell in 1993.
