Western New York may witness something that many thought would never happen in their lifetimes again – seeing Niagara Falls run dry. No water. No waterfall.

Niagara Falls is looking to rehab or replace the bridges that connect Niagara Falls, Green Island and Goat Island within the next few years. But it would not be the first time the Falls have run dry.

In 1969, the US Army Corps of Engineers created a temporary dam to stop the flow over the American side, so they can study the erosion.

The cofferdam took three days of 11-hour shifts and 30 workers to complete and consisted of boulders and fill.

It took 1,264 truck loads of fill to stop the flow of water, which was consisted of 27,800 tons of rock and earth to build the cofferdam and included a fence along the brink of the Falls for safety measures.
