Bolgoda Wetlands

The Bolgoda Lake is a shallow brackish water body in the Bolgoda watershed that is located between the southern border of the Kalu Ganga basin and the northern border of the Kelani river basin in the wet zone of the country. It is categorised as a semi-closed lagoon, as it is not connected to the sea throughout the year.

Wetland Cluster within Bundala National Park

The wetlands within the Bundala National Park consist of 4 shallow brackish water lagoons, salt marshes, mangroves, salterns, seasonal water holes/tanks and streams and the seashore. The adjacent seacoast and surrounding terrain is generally flat with sand dunes and sparse dry evergreen scrub. This biologically rich area is an internationally important wintering ground for migratory water birds, the highlight being the Greater Flamingo (Phoenicopterus ruber). In 1991, Bundala became the first wetland to be declared as a Ramsar site in Sri Lanka.

Colombo Flood Detention Areas

The Colombo marshes constitute three interconnected marshes that form a unique environment in the Greater Colombo area. The marshes are extremely important for flood detention within the Colombo City. They are a part of a large marsh system connected to the Attidiya and Bellanwila Sanctuary and also provide refuge for wildlife within the urban areas of Colombo. However, due to their urban location, the marshes are under threat from pollution and land filling.
