The Dnieper–Bug estuary (Ukrainian: Дніпровсько-Бузький лиман) is an open estuary, or liman, of two rivers: the Dnieper and the Southern Bug (also called the Boh River). It is located on the northern coast of the Black Sea and is separated from it by Kinburn Spit and the Cape of Ochakiv.
|Primary inflows||Dnieper, Southern Bug|
|Max. length||63 km (39 mi)|
|Max. width||17 km (11 mi)|
|Surface area||1,006.3 km2 (388.5 sq mi)|
|Average depth||4–6 m (13–20 ft)|
|Max. depth||12 m (39 ft)|
The estuary includes two parts: the wide Dnieper estuary (55 km long, up to 17 km wide), and the narrower Bug estuary (47 km long, from 5 to 11 km wide). The average depth is 6–7 metres (20–23 ft) and the maximum depth 22 metres (72 ft).
The estuary was a naval battleground in the Russo-Turkish War of 1787–1792. The Siege of Ochakov was a key event in that war, and naval battles – which involved the Russian Dnieper Flotilla, John Paul Jones's deep-water fleet, and the Ottoman Navy – included the First Battle of the Liman on June 7, 1788, and the Second Battle of the Liman on June 16 and 17.
The ruins of Pontic Olvia are located on the right bank of the Southern Bug (Boh River), right at its mouth.
