    "Barrier-Free" Drau Power Plant Lavamünd

    Cross-river structures such as the Lavamünd hydroelectric power plant represent impassable obstacles for fish and other organisms. This prevents fish from reaching their spawning habitats, and genetic exchange is limited. According to the 2009 National Water Management Plan of the Federal Ministry of Agriculture, Forestry, Environment and Water Management, restoring river flow is a priority goal for improving the ecological status of rivers.
    At the Lavamünd power plant, the Drau's flow and thus its fish passage were restored in the area of the weir by constructing this technical fish pass.
    The term "fish pass" is actually inappropriate here, as all aquatic organisms use this migration aid.
    The bottom of the fish pass is also a valuable habitat for microorganisms and tiny organisms such as...

      ...such as larvae and fish food organisms. Therefore, experts often refer to it as a migration corridor or a migration facility.

      The fish species profile for the Drava River in this section shows a total of 36 fish species. The fish pass is of particular interest to the Danube salmon, which, as a medium-distance migrant, travels several hundred kilometers and, with a body length of 120 cm, is the largest fish species along with the catfish. However, bream, nase, and barbel also use the fish ladder.

      The slots in the pools of the fish pass keep the water flowing consistently and direct the current in an S-shape, which corresponds to the resistance behavior of natural waters like the Drava. These low flow velocities allow easy passage, especially for juvenile fish and weaker swimmers, such as bullhead.

      The total length of the Lavamünd fish pass is 295 m. A total of 74 pools...

        ...It winds its way along the river bank through a total of 74 pools with 15 resting and spawning zones, crossing the weir system and overcoming a height difference of approximately 9.60 m. The requirements for planning and construction were extremely demanding. The functionality of the fish bypass is being monitored through a newly developed fish ecological monitoring system.
        Organism migration systems such as the fish bypass at the Lavamünd weir system make the Drava River accessible to fish and other living organisms.
