Sukhyi Estuary, or Sukhyi Lyman, is on open estuary in the north-western Black Sea, near the cities of Odesa and Chornomorsk, 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. The Dalnyk River inflows to the estuary.
The modern name, "Dry Estuary", the water body have got in the time when it was isolated from the Black Sea. That time the estuary dried regularly, sometime up to 1 km² area.
