6.25 inches of rain fell in two days, the most for this week of the year since records began in 1897. The next wettest, 3.02 inches, fell in 1992.
Indian Lake’s center stands about 930 ft above sea level. Within three miles the land runs from 850 ft to 1,080 ft, a difference of 230 ft: rolling country.
Under the town center the state geologic map shows Smithville Dolomite, Powell Dolomite, Cotter Dolomite, Jefferson City Dolomite (dolostone), from the Early Ordovician, 471 to 487 million years old.
The section below crosses 4 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 49×. 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: Early Ordovician, 471 to 487 million years old. About 7 mi of the line.
Shale, limestone, sandstone. Age: Carboniferous, 299 to 324 million years old. About 7 mi of the line.
Dolostone. Age: Early Ordovician, 471 to 487 million years old. About 6 mi of the line.
Sandstone, chert. Age: Early Ordovician, 471 to 487 million years old. About 4 mi of the line.

A raindrop that lands in Indian Lake reaches the Gulf of America by way of Brush Creek, the Bourbeuse, the Meramec and the Mississippi: about 1,330 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Indian Lake; river miles along the main stem, rounded.
Indian Lake has a hot-summer humid continental climate. Summer afternoons average 88° in July; winter nights fall to about 22° in January. About 43 inches of rain fall in a normal year.
On November 14 Indian Lake normally reaches 56° and falls to 36°. The record high is 78°, in 2025; the record low 11°, in 2018. The most rain on this date, 2.41 in, fell in 2020.
