4.02 inches of rain fell in two days, the most for this week of the year since records began in 1928. The next wettest, 3.28 inches, fell in 2018.
Chesnee’s center stands about 900 ft above sea level. Within three miles the land runs from 780 ft to 990 ft, a difference of 210 ft: rolling country. The highest named summit within 15 miles is Thicketty Mountain, about 1,260 ft, 6 miles east-southeast.
Under the town center the state geologic map shows Sillimanite-mica schist and muscovite-biotite schist (mica-schist), from the Neoproterozoic to Cambrian, 487 to 1,000 million years old.
The section below crosses 5 rock units mapped at the surface.

Mica-schist. Age: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 11 mi of the line.
Biotite-gneiss. Age: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 9 mi of the line.
Mica-schist. Age: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 2 mi of the line.
Biotite-gneiss. Age: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 2 mi of the line.
Biotite-gneiss. Age: Cambrian to Ordovician, 445 to 542 million years old. About 0.9 mi of the line.

A raindrop that lands in Chesnee reaches the Atlantic Ocean by way of Little Buck Creek, Buck Creek, the Pacolet, the Broad, the Congaree, the Santee and the South Santee: about 310 river miles.
Lake on the way: Lib Pines Lake.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Chesnee; river miles along the main stem, rounded.
Chesnee has a humid subtropical climate. Summer afternoons average 89° in July; winter nights fall to about 27° in January. About 52 inches of rain fall in a normal year, with about 1 inch of snow.
On November 14 Chesnee normally reaches 63° and falls to 35°. The record high is 79°, in 1931; the record low 18°, in 1986. The most rain on this date, 1.64 in, fell in 1972.
Normals 1991–2020 and records since 1928 at Chesnee 7 WSW, 6 miles west-southwest, 150 ft lower. NOAA, through RCC-ACIS.
