The structure of its facilities, in their order from downstream:
- Vertical boat lift with a lifting height of, the height can change along with the water level of the downstream and can reach ;
- Concrete bridge navigable aqueduct for the passage of ships to the boat lift of the second level;
- Second vertical boat lift with a lifting height of ;
- Navigable aqueduct of the second level for the passage of ships;
- Tunnel for the passage of ships from the aqueduct of the second level towards the upstream;
- Vertical boat lift of the upstream pool, the height of the descent can change along with the water level in the reservoir and can reach.
