In April 1971, Quebec Premier Robert Bourassa unveiled plans for the construction of what became the James Bay complex, one of the world’s largest assemblages of hydroelectric power stations and waterworks. In May 1972, the decision was made to built four generating stations on the La Grande River and further to divert the Eastmain and Caniapiscau rivers into the La Grande watershed. The project company was Société d'énergie de la Baie James controlled by Hydro-Québec. Construction of a 700km access road was begun in 1971 and completed in Oct 1974 at a cost of $C400mn. In the following two years, heavy equipment was brought north and construction got underway.
