The Brazeau 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.
−4° on Nov. 13, 1986, the coldest reading for this week of the year since 1959. Next is −3° in 1959.
Brazeau’s center stands about 860 ft above sea level. Within three miles the land runs from 800 ft to 940 ft, a difference of 140 ft: gently rolling country. The highest named summit within 15 miles is Thunder Mountain, about 1,450 ft, 14 miles north-northwest.
Under the town center the state geologic map shows Mafic to felsic metavolcanic rocks, from the Paleoproterozoic, 1.6 to 2.5 billion years old.
The section below crosses 6 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.
Sandstone. Age: Cambrian, 487 to 542 million years old. About 6 mi of the line.
Basalt, andesite. Age: Paleoproterozoic, 1.9 to 1.9 billion years old. About 6 mi of the line.
Dolostone. Age: Early Ordovician, 471 to 487 million years old. About 5 mi of the line.
Metavolcanic. Age: Paleoproterozoic, 1.6 to 2.5 billion years old. About 4 mi of the line.
Granite. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 3 mi of the line.
Rhyolite. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 0.6 mi of the line.

A raindrop that lands in Brazeau reaches Lake Michigan by way of Whisky Creek, South Branch Beaver Creek, Beaver Creek and the Peshtigo: about 45 river miles. From there it moves on through the Great Lakes, over Niagara Falls and down the St. Lawrence to the Atlantic.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Brazeau; river miles along the main stem, rounded.
Brazeau has a warm-summer humid continental climate. Summer afternoons average 79° in July; winter nights fall to about 5° in January. A normal year brings about 57 inches of snow; with the rain, that comes to about 32 inches of water.
On November 14 Brazeau normally reaches 42° and falls to 25°. The record high is 68°, in 1999; the record low 7°, in 1965. The most rain on this date, 0.52 in, fell in 1994.
