Lake Arthur’s center stands about 12 ft above sea level. Within three miles the land runs from 0 ft to 50 ft, a difference of 50 ft: nearly flat ground. Open water lies within three miles.
Under the town center the state geologic map shows Prairie Terraces (clay, silt, sand), from the Pleistocene, less than 2.6 million years old.
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 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, sand. Age: Pleistocene, less than 2.6 million years old. About 16 mi of the line.
Clay, silt. Age: Holocene, less than 12,000 years old. About 2 mi of the line.

A raindrop that lands in Lake Arthur reaches the Gulf of America by way of Lake Arthur and the Mermentau: about 50 river miles.
Lake on the way: Lake Arthur.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Lake Arthur; river miles along the main stem, rounded.
Lake Arthur has a humid subtropical climate. Summer afternoons average 92° in August; winter nights fall to about 43° in January. About 60 inches of rain fall in a normal year.
On November 14 Lake Arthur normally reaches 72° and falls to 51°. The record high is 85°, in 2005; the record low 27°, in 2019. The most rain on this date, 2.21 in, fell in 1929.
