which are not only pollutants to reduce the value of water resource but also nutrients for algaegrowth that debases water quality. Several methods have been used to judge the eutrophicationgrades of lakes, but the judgment results can be different with one another even under samecoditions because each method is different in judgment items and their standards.therefore, developed in this study with the application of fuzzy theory. This method allowsdecision makers to represent the uncertainties (differences) of results by the existing judgmentmethods and also incorporate associated uncertainties directly into the judgment process, so thejudgment results can be made that are more realistic and consistent than those made withouttaking uncertainty in account.
