Editing Franktown, Colorado (section)

===Castlewood Dam collapse===
The Castlewood Dam was built in 1890, about five miles south of Franktown on Cherry Creek. The barrier stored enough water to irrigate 30,000 acres of farmland. The dam began leaking the year it was completed, and was serious enough that a hundred-foot section crumbled in 1897. Although its builders vouched for the structure's integrity, the dam continued to leak sporadically for decades. Finally, on August 3, 1933, Castlewood Dam collapsed, sending a billion-gallon torrent toward Denver. Only two people drowned, thanks to a switchboard operator's life-saving calls, but the flood devastated farms in this area and tore out six bridges in Denver, thirty miles downstream. The dam's remains can still be visited in nearby [[Castlewood Canyon State Park]].<ref>{{cite web |last1=Rudolph |first1=Katie |title=August 3, 1933: Castlewood Dam Breaks, Floods Denver |url=https://history.denverlibrary.org/news/august-3-1933-castlewood-dam-breaks-floods-denver |website=Denver Public Library |access-date=11 November 2024}}</ref>
