[1] It is surrounded by two branches of the Danube, named "Borcea" and "Dunărea Veche".
The average height is 10 to 17 metres (33 to 56 ft).
Originally, a wetland, the island was covered with marshes, woods, lakes, and ponds, but some of the land was reclaimed for agriculture.
Occasionally, some of these regions are still flooded.
