Project summary

Edit project overview to modify the project summary.


The goal of this measure is an about 900 m long widening, a few meters downstream of the measure Gosdorf I, which was implemented in the first border-Mur-project (an Interreg IIIa project). The extension of dissolving the "shore corset" of the Mur and the initiation of typical river habitats shall promote the dynamic development and contribute to a fully revitalised section. At normal water levels the side-arm serves as a retreat area for small fish species in the river Mur (standing water zone).
