Brief_description
An IBA. An open estuary with mud and sandbanks. Counts began in summer 1996 and have yielded good numbers of a reasonable variety of waterbirds, including 10 Palearctic shorebird species (high counts of Ringed and Grey Plovers are noteworthy). Counts of White Pelican, cormorants, South African Shelduck, Whitefronted and Kittlitz's Plovers, and Swift Tern, are higher in summer, whereas counts of Sacred Ibis, Lesser Flamingo, most waterfowl, Avocet, Blackwinged Stilt and gulls are higher in winter. Good numbers of Avocet are recorded. Severe threats are dam building and water abstraction by riparian landowners. Disturbance by fishermen in 4x4 vehicles is an important threat, and net fishing by the local community is a mild threat.
