The project team screened available technologies to reduce the volume of leakage, which was believed to result from deterioration of the copper strip waterstops originally installed during construction of the dam. The selected solution was to install an inflatable waterstop seal system, which was installed in four of the joints with the highest observed water leakage rates into the drainage gallery. Seepage water flow was recorded before and after installation of new waterstop seals to document the effectiveness of the seals to reduce leakage through the joints. A significant decrease in water flow was achieved – up to 95% along one of the joints, with an average reduction of approximately 60% across the other joints
