74° on Nov. 11, 2020, the hottest reading for this week of the year since 1948. Next is 74° in 2022.
Lakeville’s center stands about 850 ft above sea level. Within three miles the land runs from 810 ft to 910 ft, a difference of 100 ft: gently rolling country.
Under the town center the state geologic map shows Ellsworth Shale, from the Devonian to Carboniferous, 324 to 422 million years old.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 64×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Shale. Age: Devonian to Carboniferous, 324 to 422 million years old. About 24 mi of the line.

A raindrop that lands in Lakeville reaches the Gulf of America by way of the Yellow, the Kankakee, the Illinois and the Mississippi: about 1,630 river miles.
Lake on the way: Peoria 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 Lakeville; river miles along the main stem, rounded.
Lakeville has a warm-summer humid continental climate. Summer afternoons average 82° in July; winter nights fall to about 15° in January. A normal year brings about 37 inches of snow; with the rain, that comes to about 42 inches of water.
