The Lake Lafayette 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.
80° on Nov. 14, 1964, the hottest reading for this week of the year since 1893. Next is 80° in 1999.
Lake Lafayette’s center stands about 890 ft above sea level. Within three miles the land runs from 790 ft to 960 ft, a difference of 170 ft: gently rolling country.
Under the town center the state geologic map shows Pleasanton Group (shale, sandstone), from the Carboniferous, 299 to 324 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.
Limestone, shale. Age: Carboniferous, 299 to 324 million years old. About 13 mi of the line.
Limestone, shale. Age: Carboniferous, 299 to 324 million years old. About 5 mi of the line.
Shale, sandstone. Age: Carboniferous, 299 to 324 million years old. About 5 mi of the line.

A raindrop that lands in Lake Lafayette reaches the Gulf of America by way of East Fork Sni-A-Bar Creek, Sni-A-Bar Creek, the Missouri and the Mississippi: about 1,510 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 Lake Lafayette; river miles along the main stem, rounded.
Lake Lafayette has a hot-summer humid continental climate. Summer afternoons average 90° in July; winter nights fall to about 18° in January. About 42 inches of rain fall in a normal year.
On November 14 Lake Lafayette normally reaches 56° and falls to 33°. The record high is 80°, in 1999; the record low 6°, in 2019. The most rain on this date, 1.87 in, fell in 1913.
