3.59 inches of rain fell in two days, the most for this week of the year since records began in 1960. The next wettest, 2.87 inches, fell in 2011.
Whitewater’s center stands about 370 ft above sea level. Within three miles the land runs from 340 ft to 530 ft, a difference of 190 ft: gently rolling country. The highest named summit within 15 miles is Turkey Hill, about 760 ft, 12 miles northwest.
The section below crosses 4 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 43×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Dolostone. Age: Early Ordovician, 471 to 487 million years old. About 13 mi of the line.
Clay, silt, sand. Age: Holocene, less than 12,000 years old. About 9 mi of the line.
Dolostone, sandstone, limestone. Age: Early Ordovician to Middle Ordovician, 459 to 487 million years old. About 1 mi of the line.
Clay, sand. Age: Late Cretaceous, 66 to 100 million years old. About 0.9 mi of the line.

A raindrop that lands in Whitewater reaches the Gulf of America by way of Upper Whitewater Creek, the Castor River Diversion Channel and the Mississippi: about 1,040 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Whitewater; river miles along the main stem, rounded.
Whitewater has a humid subtropical climate. Summer afternoons average 89° in July; winter nights fall to about 26° in January. About 48 inches of rain fall in a normal year.
On November 14 Whitewater normally reaches 57° and falls to 37°. The record high is 80°, in 1964; the record low 13°, in 1986. The most rain on this date, 1.34 in, fell in 2011.
Normals 1991–2020 and records since 1960 at Cape Girardeau Faa Airport, 12 miles east. NOAA, through RCC-ACIS.
