Manyas Lake (Kuş Lake)

Year of compilation: 2000

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.

Pressure/threats to key biodiversity
Artificially high water-levels have resulted in the loss of feeding marshes. Nesting trees in the National Park have also begun to die as a result of prolonged inundation. Agricultural, industrial and household pollution enters the lake in large quantities. Due to over-fishing, disease, pollution and possibly the effects of the changing water regime, fish catches have declined drastically. Fish migration into the lake is now impossible following the construction of a regulator.
