Torgelow Weir, Mecklenburg-Vorpommern
Removal for re-naturalisation purposes
Torgelow Weir was developed in the 1970s from an adjustable sluice structure into a simple weir. Since then, transverse structures have made it practically impassable for aquatic species. Two solutions to this problem were proposed, considering both ecological and hydrological aspects, and an approach of deconstructing the weir and thus re-establishing the ecological passability that was previously lost was chosen. The work was carried out with the goal of ensuring that fish would be able to pass up the river on at least 300 days per year, considering the expected flow rates of 2 to 6 m3/s, proper hydraulic functioning and flood protection issues.
