Lake Razelm
lagoon
Lake Razelm or Lake Razim (Romanian: Limanul Razim, Limanul Razelm) is a large freshwater lagoon on the shores of the Black Sea in Romania, south of the Danube Delta and part of its World Heritage Site. It is the largest liman in Romania.
The name is also sometimes applied to the complex it forms with several other limans and lagoons. This complex can be separated into two subgroups. The northern subgroup contains fresh water Razelm and Lake Golovița, which are connected by a channel 3.1 km (1.9 mi) wide, whereas the southern group is made up of salt lakes. All these lakes cover an area of about 1,000 km2 (390 sq mi), of which 400 km2 (150 sq mi) is the area of Lake Razelm alone.
Ecology
When the Razelm/Golovița system was closed off from the sea in the late 1970s, this resulted in several changes to the ecological conditions of the system, including a decrease in salinity to almost zero, an increase in refreshment time to over a year, and episodes of eutrophication. Despite this environmental degradation, the system remains an important habitat. Three families of cockles could be found in Romania in the 1960s, and the two that remain are found only in Razelm (albeit at reduced densities). Popina Island at the north end of the lake is an important refuge for many bird species and invertebrates.

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
