3° on Nov. 13, 2019, the coldest reading for this week of the year since 1949. Next is 10° in 1959.
Beaverdam’s center stands about 860 ft above sea level. Within three miles the land runs from 810 ft to 930 ft, a difference of 120 ft: gently rolling country.
Under the town center the state geologic map shows Salina Group (dolostone), from the Silurian, 422 to 445 million years old.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 63×. 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: Silurian, 422 to 445 million years old. About 24 mi of the line.

A raindrop that lands in Beaverdam reaches Lake Erie by way of Little Riley Creek, Riley Creek, the Blanchard, the Auglaize and the Maumee: about 140 river miles. From there it moves on through the Great Lakes, over Niagara Falls and down the St. Lawrence to the Atlantic.
65 miles of the trip are on the Maumee.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Beaverdam; river miles along the main stem, rounded.
Beaverdam has a hot-summer humid continental climate. Summer afternoons average 84° in July; winter nights fall to about 19° in January. A normal year brings about 32 inches of snow; with the rain, that comes to about 39 inches of water.
On November 14 Beaverdam normally reaches 50° and falls to 34°. The record high is 72°, in 1971; the record low 11°, in 1986. The most rain on this date, 1.60 in, fell in 1993.
Normals 1991–2020 and records since 1949 at Pandora, 8 miles north. NOAA, through RCC-ACIS.
