6.05 inches of rain fell in two days, the most for this week of the year since records began in 1903. The next wettest, 3.35 inches, fell in 1994.
Leonard’s center stands about 730 ft above sea level. Within three miles the land runs from 640 ft to 740 ft, a difference of 100 ft: gently rolling country.
Under the town center the state geologic map shows Gober Chalk and Roxton Limestone, from the Late Cretaceous, 66 to 100 million years old.
The section below crosses 3 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.
Chalk. Age: Late Cretaceous, 66 to 100 million years old. About 11 mi of the line.
Claystone. Age: Late Cretaceous, 66 to 72 million years old. About 9 mi of the line.
Fine-detrital, coarse-detrital. Age: Holocene, less than 12,000 years old. About 4 mi of the line.

A raindrop that lands in Leonard reaches Galveston Bay and the Gulf of America by way of Arnold Creek, Indian Creek, the East Fork Trinity and the Trinity: about 490 river miles.
Lakes on the way: Woodlands Golf Course Lake, Lavon Lake and Corder Lake.
220 miles of the trip are on the Trinity.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Leonard; river miles along the main stem, rounded.
Leonard has a humid subtropical climate. Summer afternoons average 94° in July; winter nights fall to about 33° in January. About 46 inches of rain fall in a normal year, with about 1 inch of snow.
On November 14 Leonard normally reaches 65° and falls to 43°. The record high is 86°, in 1955; the record low 19°, in 1908. The most rain on this date, 3.30 in, fell in 1994.
Normals 1991–2020 and records since 1903 at Bonham 3 NNE, 18 miles north-northeast, 130 ft lower. NOAA, through RCC-ACIS.
