Editor's Note: I'm on a break so I'm sharing former posts for your consideration and enlightenment.
I was stationed at Ft. Leonard Wood, Missouri in 1969.That’s where the Army Corps of Engineers was located. It served as a key hub for combat engineering, construction, and geospatial skills, while hosting the Prime Power School, the 1st Engineer Brigade, and the 35th Engineer Brigade (my unit)
I was training to be a combat engineer destined to go to Vietnam. My more fortunate comrades stayed stateside and worked on a massive project.
In 1969, the Army Corps of Engineers accomplished an awesome feat: They turned off Niagara Falls!
The project involved diverting the Niagara River to the Horseshoe Falls to study the accumulated debris and see if there was any structural damage.
Starting June 9, 1969, the Albert Elia Construction Company built a 600-foot-wide cofferdam using over 27,800 tons of rock to dewater the iconic falls.
The project was finished in December 1969. The amazing feat was completed in just six months.
(Editor's note: Some informative articles on the project have appeared in Amusing Planet magazine (2016); the Smithsonian Magazine (2019); National Geographic (2023) and History.com (2024.)
As it Stands, don't be concerned about Niagara Falls going dry in our lifetime because experts say the massive monument to American engineering will exist in its current form for another 50,000 years before transforming into a series of rapids.
