4.55 inches of rain fell in two days, the most for this week of the year since records began in 1893. The next wettest, 2.67 inches, fell in 1987.
Water Valley’s center stands about 300 ft above sea level. Within three miles the land runs from 260 ft to 490 ft, a difference of 230 ft: rolling country. The highest named summit within 15 miles is Thacker Mountain, about 630 ft, 13 miles north-northeast.
Under the town center the state geologic map shows Tallahatta formation and Neshoba sand (claystone, clay), from the Eocene, 34 to 56 million years old.
The section below crosses 3 rock units mapped at the surface.

Claystone, clay. Age: Eocene, 34 to 56 million years old. About 16 mi of the line.
Sand, clay. Age: Eocene, 34 to 56 million years old. About 6 mi of the line.
Sand, clay. Age: Eocene, 34 to 56 million years old. About 2 mi of the line.

A raindrop that lands in Water Valley reaches the Gulf of America by way of Town Creek, Otoucalofa Creek, the Yocona, the Tallahatchie, the Yazoo and the Mississippi: about 740 river miles.
Lake on the way: Enid Lake.
450 miles of the trip are on the Mississippi.

Water Valley has a humid subtropical climate. Summer afternoons average 91° in August; winter nights fall to about 30° in January. About 59 inches of rain fall in a normal year, with about 1 inch of snow.
On November 14 Water Valley normally reaches 65° and falls to 38°. The record high is 86°, in 1955; the record low 20°, in 1940. The most rain on this date, 4.30 in, fell in 1957.
