Lake Khanka
Lake Khanka is a broad, shallow lake in the lowlands of the Ussuri basin. Many rivers flow into it, but only the Songacha carries its waters out towards the Ussuri and the Amur. Marshes and wet meadows surround the lake, providing feeding and nesting grounds for waterbirds. The lake’s water level and the extent of its wetlands change with the seasons, making the shore a meeting place of open water, reed beds and grassland.
