Sukhyi Estuary, or Sukhyi Liman (Ukrainian: Сухий лиман - dried estuary), is on open estuary in the north-western Black Sea, near the cities of Odessa and Illichivsk, Ukraine. In 1957 the estuary was connected to the sea via 14-m depth navigation canal, therefore the water body de facto transformed to the marine bay. Upper site of the estuary is more shallow, up to 1.5 m depth. Northern and western parts are separated by artificial dam and transformed to fresh water ponds.
