Site description Lake Tunis is a large, shallow lagoon, possibly a former mouth of the Medjerda river, once connected to the sea, but now separated from it on the eastern side by the coastal dunes on which Carthage and La Goulette stand. Tunis, the capital, is situated on higher ground to the west of the lake, and is gradually spreading all round it, joining up with Radès on the southern side. The lake is bisected by a ship canal and motorway. In the northern half of the lake is the island of Chikly which has a ruined Spanish fortress on it. The southern half of the lake includes the former salt-production pans at Radès/Mégrine. The lake formerly received most of the sewage effluent and rainwater run-off from Tunis, but in the 1960s and 1970s, a clean-up operation was carried out, with waste-water being piped to a treatment station at Ariana, and circulation of water in the shallow lake improved. In the 1980s, most of the northern shores of the lagoon were reclaimed for urban expansion, destroying all natural habitat. The same has occurred in the late 1990s in the southern half of the lagoon, and the saltpans have been closed and filled in. The current ornithological status of the lake is uncertain, as the reclamation work on the south of the lake is still in progress, but it is likely that it will retain very little of its former ornithological interest, although some birds originating from nearby Sebkhet Sedjoumi and Ariana may still occur.
