4.39 inches of rain fell in two days, the most for this week of the year since records began in 1901. The next wettest, 3.50 inches, fell in 2009.
Troutman’s center stands about 920 ft above sea level. Within three miles the land runs from 770 ft to 970 ft, a difference of 200 ft: gently rolling country. The highest named summit within 15 miles is Anderson Mountain, about 1,570 ft, 15 miles southwest.
The section below crosses 8 rock units mapped at the surface.

Mica-schist. Age: Neoproterozoic, 542 to 1,000 million years old. About 4 mi of the line.
Granite. Age: Early Pennsylvanian to Permian, 270 to 320 million years old. About 3 mi of the line.
Granitic. Age: Late Mississippian to Permian, 265 to 325 million years old. About 2 mi of the line.
Metadiorite. Age: Neoproterozoic to Paleozoic, 252 to 1,000 million years old. About 2 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 Troutman reaches the Atlantic Ocean by way of Lake Norman, the Catawba, the Wateree, the Congaree, the Santee and the South Santee: about 340 river miles.
Lakes on the way: Lib Pines Lake and Lake Norman.
95 miles of the trip are on the Catawba.

Troutman has a humid subtropical climate. Summer afternoons average 87° in July; winter nights fall to about 26° in January. About 47 inches of rain fall in a normal year, with about 5 inches of snow.
On November 14 Troutman normally reaches 60° and falls to 34°. The record high is 81°, in 1999; the record low 17°, in 2013. The most rain on this date, 1.41 in, fell in 1972.
