The Quebec utility will provide assistance with repairing AAR damage to the concrete structures, reducing the cost of renovating the dam.

160-514: The entire structure essentially cutting the dam in half. This allows the dam to continue expanding whilst limiting internal stresses on the structure. The reduced lifespan of the spillway and dam was first brought to the attention of the provincial government in 2000 when projections by NB Power at that time had placed the dam's end-of-life at 2028, instead of the original 100-year lifespan of 2068. NB Power officials would not say at that time how much it would cost, nor when those costs would show up on
