The Oakdale 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.
25° on Nov. 15, 1969, the coldest reading for this week of the year since 1952. Next is 25° in 2019.
Oakdale’s center stands about 120 ft above sea level. Within three miles the land runs from 100 ft to 170 ft, a difference of 70 ft: gently rolling country.
Under the town center the state geologic map shows Intermediate Terraces (clay, silt), 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 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, silt. Age: Pleistocene, less than 2.6 million years old. About 11 mi of the line.
Clay, silt, sand. Age: Pleistocene, less than 2.6 million years old. About 4 mi of the line.
Clay. Age: Holocene, less than 12,000 years old. About 4 mi of the line.
Clay, silt, sand. Age: Pleistocene, less than 2.6 million years old. About 3 mi of the line.
Clay, silt. Age: Pleistocene, less than 2.6 million years old. About 2 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.

A raindrop that lands in Oakdale reaches the Gulf of America by way of West Fork Caney Creek, Caney Creek, Castor Creek, the Bayou Nezpique and the Mermentau: about 140 river miles.
Lake on the way: Lake Arthur.
50 miles of the trip are on the Bayou Nezpique.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Oakdale; river miles along the main stem, rounded.
Oakdale has a humid subtropical climate. Summer afternoons average 91° in August; winter nights fall to about 39° in January. About 62 inches of rain fall in a normal year.
On November 14 Oakdale normally reaches 69° and falls to 47°. The record high is 87°, in 2005; the record low 26°, in 2019. The most rain on this date, 1.76 in, fell in 1998.
