The story behind it
Long ago, Lake Razelm was a bay of the Black Sea. Over time, sand and mud piled up and cut it off from the open sea, and it became a lagoon – a lake right next to the sea. In the 1970s people closed the last gaps, so today only a narrow strip of sand separates the lake from the salty sea. Since then, water from the Danube has made the lake fresh, and almost no salt is left. Razelm is about 28 kilometres long and is joined to Lake Golovița by a wide channel. On Popina Island in the north, many birds find a safe place to rest and nest, and pelicans live in the area. For a very long time, fishing has been the main work of the people who live around the lake and in the Danube Delta. The lake is part of a World Heritage Site.

Which animals live at the lake?
