Combined Locks’s center stands about 730 ft above sea level. Within three miles the land runs from 640 ft to 810 ft, a difference of 170 ft: gently rolling country.
Under the town center the state geologic map shows Sinnipee Group (dolostone), from the Ordovician, 445 to 487 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 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.
Dolostone. Age: Ordovician, 445 to 487 million years old. About 18 mi of the line.
Shale, dolostone. Age: Ordovician, 445 to 487 million years old. About 3 mi of the line.
Dolostone. Age: Silurian, 422 to 445 million years old. About 1 mi of the line.

A raindrop that lands in Combined Locks reaches Lake Michigan by way of Garners Creek and the Fox River: about 30 river miles. From there it moves on through the Great Lakes, over Niagara Falls and down the St. Lawrence to the Atlantic.

Combined Locks has a warm-summer humid continental climate. Summer afternoons average 82° in July; winter nights fall to about 10° in January. A normal year brings about 49 inches of snow; with the rain, that comes to about 33 inches of water.
On November 14 Combined Locks normally reaches 44° and falls to 28°. The record high is 67°, in 1958; the record low 4°, in 1916. The most rain on this date, 1.60 in, fell in 1956.
