Lake Donuzlav (Russian and Ukrainian: Донузлав, Crimean Tatar: Doñuzlav), also referred to as Donuzlav Bay, is the deepest lake[1] of Crimea (27 m, 89 ft) and biggest in Chornomorske Raion (47 km2, 18 sq mi). It is a protected landscape and recreational park of the Autonomous Republic of Crimea.
The lake is as salty as the sea near its mouth but bottom springs make the water much less saline near the head.
Overview
Technically it is no longer a lake but rather a bay since 1961, when a 200-metre width canal was washed through the sandy peresyp separating it from the Black Sea, when the construction of a Soviet naval base [ru] started.[2] The peresyp length is about 12 km (7.5 mi) with widths varying between 0.3 km (980 ft) to 1 km (3,300 ft).[3][1]
The length of Donuzlav is 30 km (19 mi), a width is up to 8.5 km (5.3 mi), an area of 42 km2 (16 sq mi) and a depth is up to 27 m (89 ft).[1] It has several small bays.[1] Banks are high, steep, and winding.[1] At separate parts of the lake, a wetland vegetation is common (i.e. common reed, cattail, others).[1]
In the upper portion of the lakes are located two dams for fish farming, in the mid portion is a naval base.[1] On the banks there is a wind-powered energy station (Sakska Wind Farm [ru]) with 53 wind turbines.[1]
To the lake are headed several gulches (semi-dried streams) among which are Staryi Donuzlav, Donuzlav, Chernushka, and Burnuk.
On 5 March 2014, during the annexation of Crimea, Russian sailors scuttled two Russian Black Sea Fleet vessels, the anti-submarine ship Ochakov and the rescue tugboatShakhter, at the entrance to Donuzlav Bay to prevent Ukrainian Navy ships from accessing the Black Sea[4][5][6][7] and established the Russian naval base there, reinstating its previous name.
