Schleuse Niegripp, Navigation lock in Burg, Germany.

Schleuse Niegripp is a navigation lock in Burg that connects waterways east of the Elbe River to the main river system. The structure allows boats to pass through and navigate between the two water systems by managing the water level differences.

Schleuse Niegripp opened in 1938 after two years of construction, at the same time as the Schiffshebewerk Rothensee. It replaced the Alte Schleuse Niegripp, built between 1865 and 1872 about 2.6 km to the northeast on the former Ihlekanal, a Kuppelschleuse with three heads and two chambers of 47 m each.

The lock is named after the nearby village of Niegripp, and its chamber walls are built from steel sheet piling anchored sideways into the ground. The lock is tied into the Elbe dike, so it also protects the lower-lying canal area from flooding. A pumping station belonging to the lock keeps the water level in the canal between Niegripp and the Zerben lock and replaces water lost in each locking operation.

Visitors can watch the lock from the shore and observe boats passing through without needing access to operating areas. The location is accessible on foot and offers good viewing points along the waterfront.

The lock features variable fall heights from 5.20 meters to minus 1.35 meters due to Elbe River water level fluctuations.
