Castlewood Dam
Douglas County
Castlewood Dam was built to provide irrigation for the agricultural development of Douglas County. Constructed upon a poor foundation, it became controversial shortly after its construction in 1890.
In August of 1933, the dam collapsed sending a wall of water 1/2 mile wide and 15 feet high through Denver. This disaster resulted in the development of a comprehensive flood control program for Cherry Creek that led to the construction of the Cherry Creek Dam and reservoir.
