Paw Paw Lake’s center stands about 630 ft above sea level. Within three miles the land runs from 620 ft to 740 ft, a difference of 120 ft: gently rolling country. The highest named summit within 15 miles is Thunder Mountain, about 790 ft, 5 miles northwest.
The section below crosses 2 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 59×. 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: Carboniferous, 324 to 359 million years old. About 19 mi of the line.
Shale. Age: Late Devonian, 359 to 384 million years old. About 2 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.
Heights from Copernicus GLO-90 (a surface model: it includes buildings and tree canopy); summits from USGS GNIS; rivers from USGS NHDPlus HR; rock from the USGS State Geologic Map Compilation.
A raindrop that lands in Paw Paw Lake reaches Lake Michigan by way of the Paw Paw and the Saint Joseph: about 25 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 Paw Paw Lake; river miles along the main stem, rounded.
Paw Paw Lake has a warm-summer humid continental climate. Summer afternoons average 82° in July; winter nights fall to about 20° in January. About 35 inches of rain fall in a normal year.
On November 14 Paw Paw Lake normally reaches 50° and falls to 35°. The record high is 65°, in 2009; the record low 15°, in 1996. The most rain on this date, 0.66 in, fell in 2021.
