74° on Nov. 17, 1953, the hottest reading for this week of the year since 1892. Next is 66° in 1923.
Lake Ida’s center stands about 950 ft above sea level. Within three miles the land runs from 920 ft to 1,000 ft, a difference of 80 ft: gently rolling country. The highest named summit within 15 miles is Frenchmans Bluff, about 1,350 ft, 11 miles east-southeast.
Under the town center the state geologic map shows Calc-alkalic volcanic and volcaniclastic rocks (alkalic-volcanic), from the Neoarchean, 2.5 to 2.8 billion 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.
Metabasalt, greenstone. Age: Neoarchean, 2.5 to 2.8 billion years old. About 11 mi of the line.
Alkalic-volcanic. Age: Neoarchean, 2.5 to 2.8 billion years old. About 10 mi of the line.
Tonalite, granodiorite, diorite. Age: Neoarchean, 2.5 to 2.8 billion years old. About 1 mi of the line.
Plutonic. Age: Archean. About 1 mi of the line.
Gabbro, peridotite, pyroxenite. Age: Neoarchean, 2.5 to 2.8 billion years old. About 1 mi of the line.

A raindrop that lands in Lake Ida reaches Hudson Bay by way of the Wild Rice, the Red River of the North and the Nelson: about 1,070 river miles. Past the border it runs north through Canada to Hudson Bay.
Lake on the way: Lake Winnipeg.
400 miles of the trip are on the Nelson.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Lake Ida; river miles along the main stem, rounded.
Lake Ida has a warm-summer humid continental climate. Summer afternoons average 81° in July; winter nights fall to about −4° in January. About 25 inches of rain fall in a normal year.
On November 14 Lake Ida normally reaches 37° and falls to 19°. The record high is 67°, in 1953; the record low −20°, in 1919. The most rain on this date, 0.46 in, fell in 1971.
Normals 1991–2020 and records since 1892 at Ada, 6 miles west. NOAA, through RCC-ACIS.
