3.10 inches of rain fell in two days, the most for this week of the year since records began in 1941. The next wettest, 2.25 inches, fell in 1996.
Waterville’s center stands about 1,180 ft above sea level. Within three miles the land runs from 1,120 ft to 1,340 ft, a difference of 220 ft: rolling country. The highest named summit within 15 miles is Twin Mounds, about 1,370 ft, 14 miles east-southeast.
Under the town center the state geologic map shows Alluvium (sand, silt, clay), from the Pleistocene to Holocene, less than 2.6 million years old.
The section below crosses 5 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 53×. 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: Permian, 252 to 299 million years old. About 17 mi of the line.
Sand, silt, clay. Age: Pleistocene to Holocene, less than 2.6 million years old. About 4 mi of the line.
Shale. Age: Permian, 252 to 299 million years old. About 2 mi of the line.
Sand, silt. Age: Pleistocene, less than 2.6 million years old. About 0.6 mi of the line.
Claystone, mudstone, shale. Age: Early Cretaceous, 100 to 145 million years old. About 0.4 mi of the line.

A raindrop that lands in Waterville reaches the Gulf of America by way of the Little Blue, the Big Blue, the Kansas, the Missouri and the Mississippi: about 1,740 river miles.
Lake on the way: Tuttle Creek Lake.
1,170 miles of the trip are on the Mississippi.

Waterville has a hot-summer humid continental climate. Summer afternoons average 90° in July; winter nights fall to about 15° in January. A normal year brings about 16 inches of snow; with the rain, that comes to about 34 inches of water.
On November 14 Waterville normally reaches 55° and falls to 30°. The record high is 82°, in 1999; the record low 4°, in 1959. The most rain on this date, 0.77 in, fell in 1972.
