The Lake Wissota plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
−3° on Nov. 17, 1959, the coldest reading for this week of the year since 1893. Next is −3° in 1986.
Lake Wissota’s center stands about 920 ft above sea level. Within three miles the land runs from 880 ft to 1,030 ft, a difference of 150 ft: gently rolling country. The highest named summit within 15 miles is Moldenhauer Hill, about 1,150 ft, 14 miles south-southeast.
Under the town center the state geologic map shows Gneiss, migmatite, and amphibolite, from the Mesoarchean to Neoarchean, 2.5 to 2.9 billion years old.
The section below crosses 2 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 58×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sandstone. Age: Cambrian, 487 to 542 million years old. About 18 mi of the line.
Gneiss. Age: Mesoarchean to Neoarchean, 2.5 to 2.9 billion years old. About 7 mi of the line.

A raindrop that lands in Lake Wissota reaches the Gulf of America by way of Lake Wissota, the Chippewa and the Mississippi: about 1,820 river miles.
Lake on the way: Lake Wissota.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Lake Wissota; river miles along the main stem, rounded.
Lake Wissota has a warm-summer humid continental climate. Summer afternoons average 83° in July; winter nights fall to about 6° in January. A normal year brings about 55 inches of snow; with the rain, that comes to about 33 inches of water.
On November 14 Lake Wissota normally reaches 43° and falls to 25°. The record high is 70°, in 1990; the record low 0°, in 1959. The most rain on this date, 1.12 in, fell in 1902.
