3° on Nov. 17, 1959, the coldest reading for this week of the year since 1883. Next is 5° in 1986.
Lake Camelot’s center stands about 600 ft above sea level. Within three miles the land runs from 510 ft to 690 ft, a difference of 180 ft: gently rolling country.
The section below crosses 2 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 57×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Shale, limestone. Age: Late Pennsylvanian, 304 to 307 million years old. About 17 mi of the line.
Shale, sandstone, coal. Age: Middle Pennsylvanian to Late Pennsylvanian, 304 to 315 million years old. About 7 mi of the line.

A raindrop that lands in Lake Camelot reaches the Gulf of America by way of West Branch Lamarsh Creek, Lamarsh Creek, the Illinois and the Mississippi: about 1,350 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Lake Camelot; river miles along the main stem, rounded.
Lake Camelot has a hot-summer humid continental climate. Summer afternoons average 86° in July; winter nights fall to about 18° in January. A normal year brings about 26 inches of snow; with the rain, that comes to about 38 inches of water.
On November 14 Lake Camelot normally reaches 52° and falls to 34°. The record high is 75°, in 1971; the record low 8°, in 1940. The most rain on this date, 1.57 in, fell in 1926.
