76° on Nov. 12, 1964, the hottest reading for this week of the year since 1893. Next is 76° in 1999.
Volga’s center stands about 800 ft above sea level. Within three miles the land runs from 770 ft to 1,150 ft, a difference of 380 ft: rolling country. The highest named summit within 15 miles is Corn Hill, about 1,210 ft, 10 miles west.
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 37×. 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, dolostone. Age: Late Ordovician, 447 to 454 million years old. About 9 mi of the line.
Dolostone. Age: Late Ordovician to Silurian, 434 to 447 million years old. About 8 mi of the line.
Dolostone, limestone. Age: Late Ordovician, 447 to 459 million years old. About 5 mi of the line.
Dolostone, limestone. Age: Middle Devonian, 384 to 394 million years old. About 2 mi of the line.

A raindrop that lands in Volga reaches the Gulf of America by way of the Volga, the Turkey and the Mississippi: about 1,630 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Volga; river miles along the main stem, rounded.
Volga has a warm-summer humid continental climate. Summer afternoons average 82° in July; winter nights fall to about 6° in January. A normal year brings about 36 inches of snow; with the rain, that comes to about 39 inches of water.
On November 14 Volga normally reaches 46° and falls to 25°. The record high is 71°, in 1990; the record low −3°, in 1916. The most rain on this date, 1.05 in, fell in 1902.
Normals 1991–2020 and records since 1893 at Elkader 6 SSW, 5 miles east-southeast. NOAA, through RCC-ACIS.
