82° on Nov. 13, 1999, the hottest reading for this week of the year since 1897. Next is 78° in 1949.
Agency’s center stands about 840 ft above sea level. Within three miles the land runs from 820 ft to 1,060 ft, a difference of 240 ft: rolling country. The highest named summit within 15 miles is King Hill, about 1,070 ft, 8 miles northwest.
Under the town center the state geologic map shows Lansing Group (shale, limestone), from the Carboniferous, 299 to 324 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 54×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Limestone, shale. Age: Carboniferous, 299 to 324 million years old. About 9 mi of the line.
Shale, limestone. Age: Carboniferous, 299 to 324 million years old. About 9 mi of the line.
Shale, sandstone. Age: Carboniferous, 299 to 324 million years old. About 4 mi of the line.
Limestone, shale. Age: Carboniferous, 299 to 324 million years old. About 2 mi of the line.
Clay, silt, sand. Age: Holocene, less than 12,000 years old. About 0.5 mi of the line.

A raindrop that lands in Agency reaches the Gulf of America by way of Pigeon Creek, the Platte, the Missouri and the Mississippi: about 1,610 river miles.
1,170 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Agency; river miles along the main stem, rounded.
Agency has a hot-summer humid continental climate. Summer afternoons average 88° in July; winter nights fall to about 17° in January. About 35 inches of rain fall in a normal year.
On November 14 Agency normally reaches 54° and falls to 31°. The record high is 77°, in 1964; the record low 5°, in 1940. The most rain on this date, 1.44 in, fell in 1931.
