About Havana Street Dam
The primary purpose of Havana Street Dam is flood risk reduction. The dam is designed to control downstream flooding by temporarily storing excess water during storms and releasing it at a controlled rate. The dam is owned by U.s. Fish & Wildlife Service, Rocky Mtn Arsenal (federal). It impounds the South Platte River-tr near Commerce City.
The dam stands 14 feet tall and stretches 1,400 feet across, creates a reservoir covering 45 acres, has a maximum storage capacity of 397 acre-feet, and collects water from a drainage area of 4 square miles. Completed in 1975, the structure is well into its service life at over 50 years old.
