Thanks to the operation of locks and sluices, the water line overcomes a total difference in the level of 54.04 m (from the peak calculation to Biebrza – 14.81 m and to Niemen – 39.23 m). The water demand is at the top of Serwy Lake.
In addition to using the scheme of the system’s operation, the course and division of the locks along the route, the location and principles of the construction of damming structures (locks and sluices), and even the profile of the ditches, not subject to major changes from the moment they are built. System devices according to engineering systems of the 19th century.
You can still pay attention to the work of the lock operators, who – similarly like a century and a half ago – raise the gates with manual levers, opening the gaps in the turns, but the water fills the chamber until it is level with the reservoir located above, and then they open the strong wooden towers, pushing the drawbars with their arms.
The constant navigability of the Augustów Canal in Poland is maintained.
