74° on Nov. 16, 1993, the hottest reading for this week of the year since 1888. Next is 73° in 2020.
Coventry Lake’s center stands about 610 ft above sea level. Within three miles the land runs from 290 ft to 760 ft, a difference of 470 ft: hilly country. The highest named summit within 15 miles is Snow Hill, about 1,230 ft, 14 miles north-northeast.
Under the town center the state geologic map shows Hebron Gneiss (schist, calc-silicate-rock), from the Neoproterozoic, 542 to 1,000 million years old.
The section below crosses 9 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 25×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Schist, calc-silicate-rock. Age: Neoproterozoic, 542 to 1,000 million years old. About 6 mi of the line.
Arkose, siltstone. Age: Early Jurassic, 175 to 202 million years old. About 4 mi of the line.
Schist. Age: Neoproterozoic, 542 to 1,000 million years old. About 3 mi of the line.
Calc-silicate-gneiss. Age: Neoproterozoic, 542 to 1,000 million years old. About 3 mi of the line.
Biotite-gneiss. Age: Devonian, 359 to 422 million years old. About 2 mi of the line.
Gneiss, schist. Age: Neoproterozoic, 542 to 1,000 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. 3 smaller units along the line are not listed.

A raindrop that lands in Coventry Lake reaches Long Island Sound and the Atlantic Ocean by way of Mill Brook, the Willimantic, the Shetucket and the Thames: about 45 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Coventry Lake; river miles along the main stem, rounded.
Coventry Lake has a hot-summer humid continental climate. Summer afternoons average 81° in July; winter nights fall to about 19° in January. A normal year brings about 39 inches of snow; with the rain, that comes to about 49 inches of water.
On November 14 Coventry Lake normally reaches 51° and falls to 34°. The record high is 67°, in 1902; the record low 10°, in 1905. The most rain on this date, 2.21 in, fell in 1937.
Normals 1991–2020 and records since 1888 at Storrs, 6 miles east-northeast. NOAA, through RCC-ACIS.
