Huge irrigation projects play important role in activities carried out to diversify and increase agricultural production in Turkish agriculture. These projects also offer enormous possibilities for increasing economic efficiency and incomes in rural areas and undeveloped regions. The Lower Seyhan Irrigation Project, which is considered as one of the most progressive irrigation projects of Turkey, is a multipurpose project implemented for irrigation, drainage, flood control and hydroelectric energy production. It is well known that this irrigation project realized in The Lower Seyhan Plain has resulted in important achievements in increased yields, employment and economic welfare as well as reduction of social problems. However, despite of all these positive accomplishments, there also exist some problems such as excessive water use, high water tables, salinity and insufficient water measurements. This study seeks the determination of the level of implementation of the LSP project and its contribution to income product generation.
