The Lakeway 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.
24° on Nov. 14, 2018, the coldest reading for this week of the year since 1942. Next is 25° in 2014.
Lakeway’s center stands about 830 ft above sea level. Within three miles the land runs from 630 ft to 1,100 ft, a difference of 470 ft: hilly country. The highest named summit within 15 miles is Shingle Hills, about 1,420 ft, 7 miles southwest.
Under the town center the state geologic map shows Glen Rose Limestone (limestone, marlstone), from the Early Cretaceous, 100 to 145 million years old.
The section below crosses 2 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 26×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Limestone, marlstone. Age: Early Cretaceous, 100 to 145 million years old. About 19 mi of the line.
Limestone, dolostone, marl. Age: Early Cretaceous, 100 to 145 million years old. About 3 mi of the line.

A raindrop that lands in Lakeway reaches the Gulf of America by way of Hurst Creek and the Colorado: about 330 river miles.
Lake on the way: Lake Marble Falls.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Lakeway; river miles along the main stem, rounded.
Lakeway has a humid subtropical climate. Summer afternoons average 97° in August; winter nights fall to about 38° in January. About 36 inches of rain fall in a normal year.
On November 14 Lakeway normally reaches 72° and falls to 47°. The record high is 89°, in 2020; the record low 24°, in 2018. The most rain on this date, 0.87 in, fell in 1998.
Normals 1991–2020 and records since 1942 from the Austin-Bergstrom Airport Area threaded record (Austin-Camp Mabry, 14 miles east-southeast, 160 ft lower). NOAA, through RCC-ACIS.
