Image from the Danube Delta

The Danube Delta (Romanian: Delta Dunării pronounced [ˈdelta ˈdunərij]; Ukrainian: Дельта Дунаю, Del'ta Dunaju) is the second largest river delta in Europe, after the Volga Delta, and is the best preserved on the continent. The greater part of the Danube Delta lies in Romania (Tulcea county), while its northern part, on the left bank of the Chilia arm, is situated in Ukraine (Odessa Oblast). The approximate surface is 4152 km², of which 3446 km² are in Romania. If one includes the lagoons of Razim-Sinoe (1015 km² of which 865 km² water surface), which are located south of the delta proper, but are related to it geologically and ecologically (their combined territory is part of the World Heritage Site), the total area of the Danube Delta reaches 5165 km².
