Brief_description
An IBA, National Park and Ramsar site. The system includes the lagoon and floodplain of the Touw River, with a natural channel (the Serpentine) to the three interconnected lakes: Eilandvlei, Langvlei and Rondevlei. One of the few coastal lake systems in southern Africa, and an important wintering site for waterbirds. Fresh to slightly saline water; extensive fringing emergent vegetation of Phragmites, Typha, Juncus, sedges and grass, and much submerged vegetation. Globally significant numbers of Great Crested Grebe, Dabchick, Cape Shoveller and Redknobbed Coot occur, and nationally significant numbers of Blacknecked Grebe and Southern Pochard. There are also good counts of Reed Cormorant, Whitebacked Duck, Yellowbilled Duck Maccoa Duck and Moorhen. Counts of almost all waterbird species (except Palearctic migrants) peak in winter. The lakes hold good numbers of Little Bittern, Redchested Flufftail, African Rail, Black Crake and Purple Gallinule. Threats include increasing sediment and nutrient loadings, leading to eutrophication and associated expansion of Phragmites and algal blooms.
