Avoid currents caused by the power plant both above and below the canal. These may be strong above the canal.

Self-service lock. When approaching from below, there is a set of traffic lights, a waiting pier and instructions at the end of lower canal before the pipe bridge, on the right. The actual self-service starter cord, instructions and waiting pier are located on the right near the pedestrian and bicycle bridge. When approaching from above, the self-service starter cord, instructions and waiting pier have been on the left in a spot shielded from currents from the beginning of 2006. Previously, the pier was located on the opposite side, where the current caused by the power plant caused problems for boaters.

Please note: Use of the lock must always be booked in advance for towing combinations (tow boat and barge).
