Ranked among the top ten states for both disasters and dry climate, Colorado has a long history of extreme weather. On May 19, 1864, residents of the fledgling gold rush town of Denver awoke to a wall of water slamming into the city with enough force to flatten buildings and rip clothing from its victims. The infamous Big Thompson Canyon flood of 1976 killed 144 residents, tourists and campers. Per the National Center for Atmospheric Research, Coloradoans experienced twenty-two floods with contemporary monetary losses of $2 million or more since the flood of 1864. And as the population continues to grow, the loss of lives, property, crops and livestock may increase. Local author Darla Sue Dollman, who witnessed and survived many of the contemporary disasters, examines the state’s most catastrophic flash floods from 1864 to 2013.
