Site description The IBA comprises an artificial water reservoir and adjacent meadows situated on the River Váh. The gravel shores of the reservoir support scrub and trees. Water-fringe vegetation is present, and an artificial gravel islet 3 ha in extent has been built in the middle of the reservoir. The southern part of the IBA includes wet meadows and arable land, and is divided by man-made dykes and canals. These meadows were formerly extensively grazed by cattle, and are now abandoned and overgrown with Salix scrub.

Key Biodiversity The IBA is a very important roosting site for wintering and migrating wildfowl (Anatidae) and gulls (Laridae), and supports 20,000 or more passage waterbirds on a regular basis (including Anas platyrhynchos, Aythya ferina, Aythya fuligula, Fulica atra, Larus argentatus, L. canus and L. ridibundus).
