Fish ladder KW Obermühle, CH

In July 2018, the project at the Zwatzhof power station on the Metnitz, where we were responsible for the planning and implementation of the fish pass (FAH), was completed. The climbing aid was implemented as a multi-structure slot pass according to the system enature® Fishpass.

General project data:

Fishregion Upper trout region (epirhithral)
FAH-type enature® Fishpass
Height difference at the weir 2,8 m
Slot width 15 m
Height difference slot area 19 cm

The system has become established in Austria because the double slot requires around 1/3 less water than the conventional vertical slot pass.

If you require information on the functionality of already established enature® fish passports, please contact our office.
