During the first 30 years of operation, the reservoir area is projected to increase approximately 7-8 km2 due to shoreline erosion and peatland disintegration.AreasInitial Reservoir Area: 93.1 sq. km (23,000 acres)Initial Flooded Area: 45.1 sq. km (11,100 acres)Riverbed Area: 48.0 sq. km (11,900 acres)

Note: 50th Percentile, Open Water Flow Existing Environment and Post-Project Environment

The 30-year shoreline expansion upstream, of Birthday Rapids is not a Project effect as it is predicted to occur without the Project.

Map illustrates the estimated extent of thedewatered area when the spillway is not in operation. The true extent of this area is uncertain due to the limited bathymetric data.
