71° on Nov. 11, 2020, the hottest reading for this week of the year since 1893. Next is 65° in 2002.
Eagle Lake’s center stands about 620 ft above sea level. Within three miles the land runs from 570 ft to 1,220 ft, a difference of 650 ft: hilly country. The highest named summit within 15 miles is McLean Mountain, about 1,940 ft, 13 miles west-northwest.
Under the town center the state geologic map shows Devonian Seboomook Formation (mudstone, sandstone), from the Early Devonian, 410 to 414 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 18×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Mudstone, sandstone. Age: Early Devonian, 410 to 414 million years old. About 13 mi of the line.
Basalt. Age: Ordovician, 445 to 487 million years old. About 6 mi of the line.
Age: Silurian to Devonian, 359 to 445 million years old. About 5 mi of the line.
Mudstone, sandstone. Age: Ordovician, 445 to 487 million years old. About 0.3 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.

A raindrop that lands in Eagle Lake reaches the Bay of Fundy and the Atlantic Ocean by way of Pinette Brook, the Fish and the Saint John: about 300 river miles.
Lake on the way: Square Lake.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Eagle Lake; river miles along the main stem, rounded.
Eagle Lake has a warm-summer humid continental climate. Summer afternoons average 76° in July; winter nights fall to about −3° in January. A normal year brings about 99 inches of snow; with the rain, that comes to about 42 inches of water.
On November 14 Eagle Lake normally reaches 39° and falls to 23°. The record high is 58°, in 1951; the record low 0°, in 2019. The most rain on this date, 1.18 in, fell in 2003.
Normals 1991–2020 and records since 1893 at Fort Kent, 14 miles north. NOAA, through RCC-ACIS.
