Which liman is Romania's largest?

Romania’s largest liman is Lake Razelm, a freshwater lagoon on the Black Sea coast south of the Danube Delta.

A liman is a lagoon or estuary formed where a river valley becomes partly enclosed by coastal barriers. Razelm is part of the wider Razim–Sinoe lagoon system and connects with nearby Lake Golovița. The complex lies within the Danube Delta Biosphere Reserve, a wetland internationally recognized for its rich birdlife and aquatic habitats.

Razelm is sometimes confused with Lake Sinoe because both belong to the same coastal lagoon system. Their characters differ, however: the northern Razelm–Golovița group is predominantly freshwater, while several southern lagoons retain more marine influence. Engineering changes in the late 1970s reduced the system’s connection with the sea, sharply lowering salinity and altering water renewal.

Popina Island, at the northern end of the lake, provides refuge for birds and invertebrates. Fishing, reed harvesting, livestock raising and tourism remain important activities around the lagoon.
