A second controversy related to the fact that the land had been inhabited prior to its flooding, therefore the flooding resulted in the displacement of the forty or fifty residents located in the Trench. Among them were members of the Tsay Keh Dene First Nation, then known as Ingenika. The displacement had negative social impacts on the inhabitants as the loss of the land that had previously supported them meant loss of autonomy and resulted in isolation, alienation, and "social disorganization". A BC Hydro consultant admitted in 1977 that the 'isolation imposed by the reservoir had severe impacts on Ingenika society and culture".
