73° on Nov. 11, 2022, the hottest reading for this week of the year since 1948. Next is 72° in 1971.
Powers Lake’s center stands about 860 ft above sea level. Within three miles the land runs from 790 ft to 910 ft, a difference of 120 ft: gently rolling country.
Under the town center the state geologic map shows Silurian, undivided (dolostone), from the Silurian, 422 to 445 million years old.
The section below crosses 3 rock units mapped at the surface.
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 17 mi of the line.
Dolostone, limestone. Age: Silurian, 422 to 445 million years old. About 6 mi of the line.
Shale, dolostone. Age: Ordovician, 445 to 487 million years old. About 0.6 mi of the line.

A raindrop that lands in Powers Lake reaches the Gulf of America by way of East Branch North Branch Nippersink Creek, North Branch Nippersink Creek, Nippersink Creek, the Fox River, the Illinois and the Mississippi: about 1,560 river miles.
Lakes on the way: Peoria Lake and Fox Lake.
1,190 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Powers Lake; river miles along the main stem, rounded.
Powers Lake has a warm-summer humid continental climate. Summer afternoons average 81° in July; winter nights fall to about 11° in January. A normal year brings about 38 inches of snow; with the rain, that comes to about 35 inches of water.
On November 14 Powers Lake normally reaches 46° and falls to 28°. The record high is 71°, in 1989; the record low 5°, in 1986. The most rain on this date, 0.89 in, fell in 1951.
Normals 1991–2020 and records since 1948 at Burlington Wwtp, 7 miles north-northeast. NOAA, through RCC-ACIS.
