Ochtumsperrwerk, Tidal barrier in Lemwerder, Germany.
The Ochtumsperrwerk extends 1.5 kilometers across the Ochtum River mouth, featuring two 10-meter-wide openings controlled by specialized gate systems for flood management.
Construction of the barrier began in 1971 and finished in 1976, following the devastating floods of 1962 that caused casualties in the Unterweser region.
The barrier operates within an integrated network alongside the Lesum and Hunte locks, reflecting the German engineering approach to water management systems.
The structure contains a chamber lock measuring 20 meters in length and 8 meters in width to accommodate recreational boat traffic along the Ochtum River.
The barrier closes approximately 82 times annually to regulate water levels, protecting Bremen districts of Huchting and Grolland from potential flooding.
