Site description A brackish lake (6,300 ha; max. depth 30 m) fed by springs and several streams. Extensive reedbeds (Phragmites) are found along the east, south-east and northern shores. The delta consists of a labyrinth of (former) flood-plains, reedbeds, lakes and sand beaches. Arable land and forested hills surround the IBA, which also includes a few hundred hectares of Liquidambar forest. Economic activities include greenhouse farming and cattle-grazing.
