Brief_description
Open estuary and lagoon, partly within a nature reserve. Dabchick, cormorant and Greater Flamingo numbers usually greater in winter, with highest count recorded in winter 1996; numbers of Redknobbed Coot also much higher in winter 1995 and 1996 but declined drastically in 1997; numbers of waterfowl and Kittlitz's Plover peak in summer. Occurrence of Antarctic Tern noteworthy. Declines shown in number of species and in total counts, summer and winter. Important threats are dam building upstream, residential development, and overhead powerlines.
