The Great Acuna Flood
June 26, 1954 (Hurricane Alice): This storm quickly developed off Brownsville. It made landfall within 24 hours of formation. Most residents did not know about it until it was upon them. Heavy rains near Langtry resulted in 27.10" of rain at Pandale. This caused the greatest rise on the Rio Grande since 1865. The river rose 30 to 60 feet at Eagle Pass and Laredo. An 86' wall of water rushed down the Pecos River; this washed out a bridge normally 50' above it. The International Bridge at Laredo was also washed out. Most of the death and destruction occurred in Mexico.
The flood plain of the Rio Grande and the land adjacent to Arroya de Las Vacas were underwater during the flood of 1954. While the International Bridge sat above the water, the approaches to it were destroyed, rendering the bridge useless.
The 1954 flood destroyed the railroad bridge over Devil's River. In 21 hours, 18 inches of rain fell at Ozona in Crockett County on Val Verde's north border. As much as 30 inches fell in locales along the Pecos River to the west. All of the runoff funneled down the Devil's River, Pecos River and Rio Grande, causing much damage.
