In this paper; a decision support system is that designed for shallow lakes under the impact of eutrophication and climate change is presented together with its application to a hypertrophic lake that is located in the northwestern part of the Republic of Türkiye and is under the threat of aging in the following decades due to the cultural eutrophication. The lake that is an important breeding area for many bird species as well as one of the major resting area for migratory birds is under the impact of mainly diffuse emission sources of nutrient and is classified as hypertrophic according to the country’s water quality regulations. The decision support system (DSS) developed is based on non-linear mathematical programing and aims the minimization of initial investments and continuous annual expenses and utilizes the trophic status and related water quality as the main constraints. The main results of this study are the successful development of the DSS and its successful application on the decision problem of aiming feasible and sustainable trophic status of the case study area based on Carlson trophic status index (TSI). The main conclusion is that even though the related lake will stay eutrophic, the probability of a hypertrophic state can at least be reduced drastically.
