5.00 inches of rain fell in two days, the most for this week of the year since records began in 1878. The next wettest, 3.01 inches, fell in 1940.
Lake Norman of Iredell’s center stands about 800 ft above sea level. Within three miles the land runs from 750 ft to 860 ft, a difference of 110 ft: gently rolling country. The highest named summit within 15 miles is Anderson Mountain, about 1,570 ft, 9 miles west.
Under the town center the state geologic map shows Fine-grained Biotite Gneiss (biotite-gneiss), from the Neoproterozoic to Cambrian, 487 to 1,000 million years old.
The section below crosses 7 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 38×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Biotite-gneiss. Age: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 8 mi of the line.
Metadiorite. Age: Neoproterozoic to Paleozoic, 252 to 1,000 million years old. About 6 mi of the line.
Granite. Age: Early Pennsylvanian to Permian, 270 to 320 million years old. About 3 mi of the line.
Mica-schist. Age: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 3 mi of the line.
Granitic. Age: Ordovician to Devonian, 359 to 487 million years old. About 2 mi of the line.
Mica-schist. Age: Neoproterozoic to Cambrian, 487 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. 1 smaller unit along the line are not listed.

A raindrop that lands in Lake Norman of Iredell reaches the Atlantic Ocean by way of Lake Norman, the Catawba, the Wateree, the Congaree, the Santee and the South Santee: about 320 river miles.
Lakes on the way: Lib Pines Lake and Lake Norman.
95 miles of the trip are on the Catawba.

Lake Norman of Iredell has a humid subtropical climate. Summer afternoons average 90° in July; winter nights fall to about 32° in January. About 44 inches of rain fall in a normal year, with about 4 inches of snow.
On November 14 Lake Norman of Iredell normally reaches 63° and falls to 40°. The record high is 80°, in 1879; the record low 21°, in 2013. The most rain on this date, 1.23 in, fell in 1972.
