Syvash

The Syvash or Sivash , also known as the Putrid Sea or Rotten Sea , consists of a large system of shallow lagoons on the west coast of the Sea of Azov. Separated from the sea by the narrow Arabat Spit, the water of the Syvash covers an area of around 2,560 km2 and the entire area spreads over about 10,000 km2 . Its eastern connection to the Sea of Azov is called the Henichesk Strait. The Syvash borders the northeastern coast of the main Crimean Peninsula; Central and Eastern Syvash registered as wetlands of Ukraine under Ramsar Convention, after the 2014 Russian annexation of Crimea became under a territorial dispute.

The Syvash nearly cuts the Crimean Peninsula off from the mainland, serving as a natural border for its autonomous republic. The long and narrow Arabat Spit runs to its east, separating it from the Sea of Azov. The two bodies are connected in the north at the Henichesk Strait beside the port of Henichesk. To its west, the isthmus of Perekop separates it from the Black Sea and connects Crimea to Ukraine.
