    Akgöl lake is located on the coast of Göksu Delta that is the most important wetland of the Eastern Mediterranean. Akgöl that is a freshwater lake, has a depth of 40 cm and a surface area of 1,245 km2. As a result of intensive agricultural activities, annual fertilizer use is much higher than the national average in the Göksu delta. The Akgöl lake water quality is also affected by the delta agricultural activities.

    In this study, the water quality change of Akgöl was investigated depending on years. For this purpose, water samples were taken 7 times from 2006 (June), 2007 (July), 2008 (January-April), 2011(February-July), 2012 (September) in the same place. In the samples; pH, temperature, electrical conductivity (EC), salinity (Sal) and dissolved oxygen (DO), nitrate nitrogen, nitrite nitrogen, ammonium nitrogen and total phosphorus were analyzed.

    The analysis results were compared with “The Surface Water Quality Regulation Annex-5” limit values. The relationship of dissolved oxygen which is an important parameter for evaluating water quality of lakes, to other parameters (nitrate, ammonium, phosphorus, temperature, pH, and electrical conductivity) was explained by the regression analysis.

    Keywords: Akgöl lake, regression analysis, water quality.
