A Sudden Stillness
In 1969, the U.S. Army Corps of Engineers halted the flow of water over Niagara’s American Falls. This unprecedented “dewatering” allowed engineers to assess and possibly remove boulders that had halved the falls’ height since 1931. For the first time, the cascading wonder stood silent.
Crowds Gather
The transformation drew massive crowds. Over 100,000 visitors flocked to witness the falls without water, revealing a barren cliff of bedrock beneath. The sight, while not traditionally scenic, offered a rare glimpse into the natural and engineered aspects of the iconic site.
Engineering Marvel
Using a dam at Goat Island, engineers stopped 76,000 gallons of water per second, a feat that symbolized human control over nature. Ultimately, the decision was made to leave the fallen boulders, reflecting a growing environmental ethic.
A Controlled Natural Wonder
Today, Niagara Falls is shaped by both nature and human intervention. Water diversion projects reduce erosion, preserving the falls’ grandeur for tourism. Yet, even with these efforts, the falls continue to erode, inching toward an eventual and inevitable transformation.
In 1969, the U.S. Army Corps of Engineers did the unthinkable: they stopped the flow of water over Niagara's American Falls. For the first time, visitors witnessed the iconic cascade reduced to a bare cliff, drawing over 100,000 curious spectators to the site. 🧵1/4 pic.twitter.com/U9rDfTOktL
