5.00 inches of rain fell in two days, the most for this week of the year since records began in 1893. The next wettest, 4.25 inches, fell in 1929.
Oak Grove’s center stands about 410 ft above sea level. Within three miles the land runs from 270 ft to 430 ft, a difference of 160 ft: gently rolling country.
Under the town center the state geologic map shows Citronelle formation (sand, gravel), from the Pliocene to Pleistocene, less than 5.3 million years old.
The section below crosses 2 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 59×. 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: Miocene, 5.3 to 23 million years old. About 14 mi of the line.
Sand, gravel. Age: Pliocene to Pleistocene, less than 5.3 million years old. About 10 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 Oak Grove reaches the Gulf of America by way of Perkins Creek, Black Creek, Big Black Creek, the Pascagoula and the West Pascagoula: about 150 river miles.
100 miles of the trip are on Black Creek.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Oak Grove; river miles along the main stem, rounded.
Oak Grove has a humid subtropical climate. Summer afternoons average 92° in July; winter nights fall to about 38° in January. About 59 inches of rain fall in a normal year.
On November 14 Oak Grove normally reaches 70° and falls to 44°. The record high is 90°, in 1925; the record low 25°, in 1963. The most rain on this date, 3.60 in, fell in 1957.
