11° on Nov. 13, 1976, the coldest reading for this week of the year since 1896. Next is 13° in 1911.
Lake Waynoka’s center stands about 1,010 ft above sea level. Within three miles the land runs from 960 ft to 1,070 ft, a difference of 110 ft: gently rolling country.
Under the town center the state geologic map shows Preacherville Member of the Drakes Formation, Waynesville and Arnheim Formation, Undivided (shale, limestone, dolostone), from the Late Ordovician, 445 to 454 million years old.
The section below crosses 3 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 49×. 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, dolostone. Age: Late Ordovician, 445 to 454 million years old. About 17 mi of the line.
Shale, limestone. Age: Late Ordovician, 445 to 454 million years old. About 5 mi of the line.
Limestone, shale. Age: Late Ordovician, 445 to 459 million years old. About 2 mi of the line.

A raindrop that lands in Lake Waynoka reaches the Gulf of America by way of Straight Creek, the Ohio and the Mississippi: about 1,540 river miles.
970 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Lake Waynoka; river miles along the main stem, rounded.
Lake Waynoka has a hot-summer humid continental climate. Summer afternoons average 87° in July; winter nights fall to about 23° in January. About 48 inches of rain fall in a normal year.
On November 14 Lake Waynoka normally reaches 56° and falls to 34°. The record high is 81°, in 1955; the record low 14°, in 1986. The most rain on this date, 1.72 in, fell in 1951.
Normals 1991–2020 and records since 1896 at Maysville Wastewater Treatment Plant, 17 miles south, 500 ft lower. NOAA, through RCC-ACIS.
