The Emmet plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
5.64 inches of rain fell in two days, the most for this week of the year since records began in 1892. The next wettest, 4.78 inches, fell in 1935.
Emmet’s center stands about 310 ft above sea level. Within three miles the land runs from 230 ft to 330 ft, a difference of 100 ft: gently rolling country. The highest named summit within 15 miles is Rocky Mound Hill, about 500 ft, 4 miles southwest.
Under the town center the state geologic map shows Midway Group (clay, marl), from the Paleocene, 56 to 66 million years old.
The section below crosses 5 rock units mapped at the surface.
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.
Clay, marl. Age: Paleocene, 56 to 66 million years old. About 9 mi of the line.
Sand, fine-detrital. Age: Early Eocene, 48 to 56 million years old. About 6 mi of the line.
Sandstone. Age: Late Cretaceous, 66 to 100 million years old. About 5 mi of the line.
Marlstone, mudstone. Age: Late Cretaceous, 66 to 100 million years old. About 3 mi of the line.
Coarse-detrital, fine-detrital. Age: Holocene, less than 12,000 years old. About 2 mi of the line.

A raindrop that lands in Emmet reaches the Gulf of America by way of Terre Rouge Creek, the Little Missouri, the Ouachita, the Black River, the Red River, the Atchafalaya and the Lower Atchafalaya: about 580 river miles.
310 miles of the trip are on the Ouachita.

Emmet has a humid subtropical climate. Summer afternoons average 92° in July; winter nights fall to about 31° in January. About 56 inches of rain fall in a normal year, with about 2 inches of snow.
On November 14 Emmet normally reaches 65° and falls to 41°. The record high is 85°, in 1955; the record low 16°, in 2019. The most rain on this date, 1.93 in, fell in 1926.
