A fish ladder was built at Lech barrage 21 near Prittriching to improve the ecological continuity of the Lech for aquatic life. This project was initiated by Uniper Kraftwerke GmbH and planned and implemented by Bau + Plan Ingenieurgesellschaft mbH.

Details of the facility:

• Entry structure: A vertical slot pass with 32 basins serves as an entry structure for the fish.

• Near-natural channel: An existing drainage ditch was converted into a near-natural flowing water approximately 320 meters long with meander structures, widenings and pools.

• Exit structure: Another vertical slot pass with 41 basins forms the exit structure.

• Distribution lines: Steel lines with a diameter of 450 mm were installed to supply water.

These measures help to restore the migration routes for fish and other aquatic organisms and promote biodiversity in the Lech.
