Site description A shallow nutrient-rich freshwater lake (average depth 3 m) fed by groundwater and four streams. Small deltas have formed where the latter enter the lake, comprising extensive marshes and tree-lined riverbanks. Narrow belts of reed Phragmites fringe much of the lake. Water is abstracted for factory use and for irrigation. Cattle- and sheep-grazing is common along the lake shores.

Key Biodiversity This is an important site for breeding and wintering waterbirds; migrating Pelecanus onocrotalus often roost at the lake.
