Gravel banks for the head of reservoir at Melk

It is envisaged that, at the so-called "Ybbs Scheibe" (Ybbs disk) in the Melk power plant head-of-reservoir, new gravel banks will represent an expansion of the successful Danube-Ybbs LIFE+ networking project.

Structuring of the shoreline will be carried out in the slip-off bank of the "Ybbs Scheibe" between river kilometre 2057.70 and 2054.90 by means of gravel filling. A sequence of gravel banks and gravel islands will be created, through which calm flow zones will emerge, along with shallow gravel surfaces that are flooded at low and mean-flow conditions.

The main goal of this measure is improvement of the living conditions and spawning areas for fish species requiring gravelly banks and bars, such as barbel, nase, zingel and Danube streber. Gravel is being taken from the main Danube riverbed in the area of the Erlauf estuary and distributed along the left bank of the Danube near Hagsdorf according to a detailed plan. The work is expected to be completed by the end of 2018. A total of 200,000 m3 of gravel are being moved.

Downstream from the Ybbs-Persenbeug power plant (red markings) the Danube shoreline is being upgraded with gravel banks. The material for this is being taken from near the Erlauf estuary (green area).

Fish-friendly banks for the Danube between Ybbs and Melk

Dredging work begun between Melk and Ybbs

Below the Ybbs-Persenbeug power plant, the VERBUND fleet is currently working on a fish kindergarten. The fish larvae are just a few centimetres long and need still, shallow pool zones while growing up. The very structured Danube provided too few of these. LIFE+ Network Danube is closing the gap with dredging work at the "Ybbser Scheibe", the head of the Melk power plant reservoir.
