# Kopperl, Texas

Kopperl (pronounced KOP-er-ul) is an unincorporated community and census designated place (CDP) in Bosque County, Texas, United States. It lies on the northwestern end of Lake Whitney, and has an estimated population of 225.

## History

Kopperl was founded in 1881. Named after Galveston banker and railroad tycoon Moritz Kopperl, the town was established as a regional shipping point along the Gulf, Colorado and Santa Fe Railway. Its population peaked at 329 in 1904 before declining to 225 by the 1970s, a figure it has maintained fairly consistently since.
Shortly after midnight on June 15, 1960, a very rare meteorological phenomenon, a heat burst, struck the community when a dying thunderstorm collapsed over Kopperl. The storm had rained itself out, and with little to no precipitation to cool the resulting downdrafts, superheated air descended upon the community in the form of extremely hot wind gusts up to 75 mph (121 km/h). The temperature increased rapidly, reportedly peaking near 140 °F (60 °C), 20° above the official all-time high for the state of Texas and exceeding the highest official temperature recorded on Earth. The storm, known as "Satan's Storm" by locals, soon became part of local folklore.
Kopperl was the town described in "Texas Trilogy", a song by Texas native Steve Fromholz and covered by Lyle Lovett.
