After determining all the aspects of canal construction, the next most pressing issue was where would the workers for the construction come from?
During the construction of Germany's Kiel Canal, nearly 90,000 workers were employed, and it was expected that even more would be needed for the construction of the Lake Eyre Canal.
If the entire Lake Eyre Canal were to be divided into three sections and constructed simultaneously, the good news was that the construction time could be significantly reduced. The bad news was that more workers would be needed.
As for the source of these workers, Arthur had already laid out a basic plan. The recently collapsed United States actually had a large number of unemployed workers. These workers were not only an excellent source of immigrants but also potential labor for the construction of the Lake Eyre Canal.
