1976 Big Thompson River Flood
On July 31, 1976, during the celebration of Colorado’s centennial, the Big Thompson Canyon was the site of a devastating flash flood that swept down the steep and narrow canyon, claiming the lives of 143 people, 5 of whom were never found. This flood was triggered by a nearly stationary thunderstorm near the upper section of the canyon that dumped 300 millimeters (12 inches) of rain in less than 4 hours (more than 3/4 of the average annual rainfall for the area). Little rain fell over the lower section of the canyon, where many of the victims were. Around 9 p.m., a wall of water more than 6 meters (20 ft) high raced down the canyon at about 6 m/s (14 mph), destroying 400 cars, 418 houses and 52 businesses and washing out most of U.S. Route 34.[5] This flood was more than 4 times as strong as any in the 112-year record available in 1976, with a discharge of 1,000 cubic meters per second (35,000 ft³/s).

The Big Thompson flood of 1976 was the deadliest flash flood in Colorado’s recorded history. On July 31, between 12 and 14 inches of rain fell over a four-hour period in the mountains around the resort town of Estes Park. Unusual weather patterns allowed the huge storm system to stall over the area as it dumped its load
1921 Pueblo flood


Article – Untitled Article
As the torrential rains fell, the Arkansas River and Fountain Creek quickly began to swell, reaching over 15 feet in some areas before they began to recede. Within two hours from the start of the storm, the entire wholesale district and a greater part of the business district of Pueblo were flooded with water 10 feet deep. The entire Arkansas Valley, from 30 miles west of Pueblo to the Colorado–Kansas state line, was severely impacted. Hundreds of people died, with some death toll estimates as high as 1,500. The flood destroyed almost all of the downtown Pueblo area and decimated the city.

The rainfall intensity of the storms listed above was much greater than this week’s rain.
The NOAA liars who are claiming the current flood is a “biblical 1,000 year flood” should be prosecuted. They are shouting fire in a crowded theatre.
