At the time of the German Empire and in the middle of the First World War, the Lindener Hafen-Schleuse was built between 1916 and 1917 in order to overcome the difference in level between the branch canal and the 7.80 meter higher basin of the Lindener Hafen. The 85 m long and 10 m wide chamber lock was designed for the ship dimensions customary at the time, which were built with a length of 67 m and a width of 8.20 m for a loading depth of 1.75 m. The Lindener Hafen-Schleuse is too small for modern large motor cargo ships and push convoys, so that the Lindener Hafen cannot be approached by these types of ships. European ships (85 m in length) can only be funneled with a special permit. Therefore, an expansion of both the branch canal and the lock was planned, but this is now considered unlikely. In addition to the small but very modern tankers of the Sunrise series, the port of Linden is called by real vintage freighters, which supply the steel trade and transport away the scrap collected from the recycling companies.
Bathing in stagnant water such as the Linden canal is strictly forbidden, but the bank is often used by local residents in the summer months.
