Burdur Lake has lost a quarter of its water during the last 20 years. The decline in the water level is still continuing. The annual water loss of the lake is approximately 40 hm3. Under the current circumstances the decline in its water level will continue until it reaches 80 km2. At this level the water budget of the lake will balance. The main problem is that a large amount of water is extracted from its natural cycle for irrigation projects at the lake basin. The amount of water to be saved is 1.5 times the annual water loss of Burdur Lake if pressurized irrigation methods were used in place of surface irrigation methods
