Zanimljiv i nesvakidašnji poduhvat izveli su pripadnici američkog inžinjerijskog korpusa 1969-te godine. Tada su za potrebe geoloških istraživanja "presušili" Nijagarine vodopade (sa američke strane) napravivši improvizovanu branu preusmeravanjem korita reke na kanadsku stranu.
Ove raritetne fotografije zabeležili su turisti koji su se zadesili u to vreme na vodopadima....

10x10 ::Kako su to izveli. Tu je ogromna masa vode koja se krece.
Pa reke se stalno preusmeravaju dok se grade brane samo sto je sad povod bio drugi.

The Albert Elia Construction Company of Niagara Falls, New York was awarded a $445,412 contract to build and remove a 600 foot (183m) cofferdam from the mainland to the head of Goat Island in order to divert the water from the American channel. In addition, they were required to clean the surface of the river bed, scale loose rock from the face of the Falls, and install a water spray system.

Monday June 9th 1969 - The first major safety problem occurred as workers from Albert Elia Construction Company of Niagara Falls, New York pushed rocks and earth into the Niagara River at the head of Goat Island to erect the 600 foot long cofferdam in order to divert the water. A lifeline was strung by helicopter from the mainland to Goat Island before the operators began. The line was to give everyone who might fall into the treacherous water something to catch before being swept downriver in the racing current to the American Falls.

After 3 days of working two 11 hour long shifts, thirty (30) workmen from the Albert Elia Construction Company sealed off all but a small gap in the cofferdam by Thursday at 2:40 a.m. Three truck loads of fill and three boulders were pushed into place seal the cofferdam completely this morning by 10:40 a.m. The dam was now holding back the eight (Cool foot (2.4m) deep water of the Niagara River.

It took 1,264 truck loads of fill to stop the flow of water. The fill consisted of 27,800 tons of rock and earth to build the cofferdam.
