A Huge Project
Albert Elia Construction was contracted to build this cofferdam. Included in their fee of $500,000 was the task of scouring the riverbed once exposed and removing all loose rocks from the surface of the falls and installing a sprinkler system between the rocks.
Getting Started
Finally, on June 9, 1969, work began to carry out this mammoth task. They installed a lifeline across the river connecting the mainland to Goat island as a safety net. A total of almost 28,000 tons of earth and rocks was relocated upstream of the cataract.
