As part of the test, the phased opening of the segment gates at the entrance to the center pole of full disclosure (9.5 meters), providing transit through the water ready to use elements of the building: two tunnels, five-step drop and the discharge canal.

During the test was carried out continuous monitoring of the state of the shore spillway, the parameters pass costs through both the tunnel and the process of reshaping the shoreline diversion channel.
