Here’s a look back at the catastrophic failure of the Castlewood Dam on Cherry Creek, from Jeffrey Wolf writing for 9News.com. From the article:
Heavy rain put too much pressure on the Castlewood Dam, located in what is now the Castlewood Canyon State Park near Franktown. The 300 feet of rock and concrete gave out and a wall of water rushed through Cherry Creek. It flooded farmland, swept away buildings, and tore down bridges 30 miles away in downtown Denver. It was the worst flood ever in Denver and the damage was extensive.
