3.50 inches of rain fell in two days, the most for this week of the year since records began in 1980. The next wettest, 3.44 inches, fell in 2011.
Eddyville’s center stands about 500 ft above sea level. Within three miles the land runs from 350 ft to 590 ft, a difference of 240 ft: rolling country. The highest named summit within 15 miles is Crayne Knob, about 820 ft, 12 miles north.
Under the town center the state geologic map shows Ste. Genevieve and St. Louis Limestones, undivided, from the Carboniferous, 324 to 359 million years old.
The section below crosses 8 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 50×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Limestone. Age: Carboniferous, 324 to 359 million years old. About 12 mi of the line.
Conglomerate. Age: Late Cretaceous, 66 to 100 million years old. About 5 mi of the line.
Limestone, sandstone. Age: Carboniferous, 324 to 359 million years old. About 2 mi of the line.
Shale. Age: Carboniferous, 324 to 359 million years old. About 1 mi of the line.
Gravel, sand. Age: Tertiary to Holocene, less than 66 million years old. About 1 mi of the line.
Limestone. Age: Carboniferous, 324 to 359 million years old. About 1 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 2 smaller units along the line are not listed.

A raindrop that lands in Eddyville reaches the Gulf of America by way of Bards Lake, the Cumberland, the Ohio and the Mississippi: about 1,070 river miles.
Lake on the way: Bards Lake.

Eddyville has a humid subtropical climate. Summer afternoons average 88° in July; winter nights fall to about 26° in January. About 49 inches of rain fall in a normal year, with about 4 inches of snow.
On November 14 Eddyville normally reaches 58° and falls to 37°. The record high is 77°, in 1999; the record low 13°, in 1986. The most rain on this date, 1.47 in, fell in 2024.
Normals 1991–2020 and records since 1980 at Smithland Lock & Dam, 20 miles west-northwest, 140 ft lower. NOAA, through RCC-ACIS.
