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 Wylie’s center stands about 600 ft above sea level. Within three miles the land runs from 560 ft to 760 ft, a difference of 200 ft: gently rolling country. The highest named summit within 15 miles is Spencer Mountain, about 1,260 ft, 14 miles north-northwest.
Under the town center the state geologic map shows Metamorphosed quartz diorite to diorite (metadiorite), from the Neoproterozoic to Cambrian, 487 to 1,000 million years old.
The section below crosses 9 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 59×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Metadiorite. Age: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 8 mi of the line.
Metagranite. Age: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 4 mi of the line.
Metagranite, metadiorite. Age: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 4 mi of the line.
Metadiorite. Age: Neoproterozoic to Paleozoic, 252 to 1,000 million years old. About 3 mi of the line.
Granite. Age: Early Pennsylvanian to Permian, 270 to 320 million years old. About 2 mi of the line.
Mica-schist. Age: Neoproterozoic, 542 to 1,000 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. 3 smaller units along the line are not listed.

A raindrop that lands in Lake Wylie reaches the Atlantic Ocean by way of Crowders Creek, the Catawba, the Wateree, the Congaree, the Santee and the South Santee: about 280 river miles.
Lake on the way: Lib Pines Lake.
90 miles of the trip are on the Wateree.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Lake Wylie; river miles along the main stem, rounded.
Lake Wylie 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 Wylie 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.
