The objective of this study is to suggest methods for evaluating drought using groundwater level data of GIMS (National Groundwater Information Management and Service Center) and to check the applicability of the suggested methods in 2001 drought situation. It is necessary to identify threshold level of each drought classification for applying groundwater level data to evaluate drought. Two methods were suggested for identifying threshold level of each drought classification: ① Linear regression analysis between groundwater level data and MSWSI results, ② Probability analysis using multi-temporal groundwater level data. As results of two methods application, method ① had comparative high accuracy and could be applied in case of specific watersheds. Method ② could be applied in all watersheds even though there were low accuracies regionally.
