Germany: The Lock Hohenwarthe at the Midland Canal

In august 2009 we passed this lock on our way back from Berlin to the Netherlands.
The lock Hohenwarthe forms the eastern end of the Midland Canal at Suelfeld - Hohenwarthe.
The two lock chambers of the double lock Hohenwarthe are symmetrically arranged parallel to each other and each have an effective length of 190 m and a width of 12.50 m. Thus the chambers are large enough to carry all types of currently circulating freight ships.
At normal water the height difference to overcome is 18.55 m.
A 12.50 m wide middle wall separates the two lock chambers from each other. In addition to the two chambers there are three stacked staggered saving pools. So a water saving of around 60% can be achieved. The remaining 40% of the water needs are taken from the upper segment of the canal, when the ships are taken upwards. This 'lost' water is pumped back in the upper segment of the canal by means of three powerful pumps that can pump both 3.5 m³ of water per second.
