The aim of the project was to enhance the Boros-Drava oxbow’s ecological status on the Hungarian side and the Aljmaski rit’s ecological status on the Croatian side by dredging the sediment full of organic materials. In both aquatic habitats the eutrophication process had been in a well-advanced condition. On the Hungarian side the South-Transdanubian Water Management Directorate dredged 50 000 m3 sediment from the bottom of the Boros-Drava oxbow which is situated closed to the settlement called Old. Beyond the above-described project activities, new fishing piers were installed at Boros-Drava and native fish species (carp, pike, tench) were released to enhance the touristic attractiveness of the area. On Croatian side on the so-called Aljmaski rit aquatic habitat 4 hectares wetland and on Hungarian side 3.2 hectares got better conservation status by the sediment removal. Due to these works the water flow is better ensured in these aquatic habitats and thus their ecological status is expected to increase on the long run. This will be envisaged by a newly established eco-monitoring system.
