%X Drought is a natural disaster resulting from a significant reduction of rainfall based on long-year averages. Drought analysis is required to determine the drought periods and to reduce harmful effects of drought. In this study, the monthly streamflow data for the period between 1936 and 2011 were obtained from the current observation station (1801) within the G£¿ksu-Himmetli sub-basin of the Seyhan basin was used. Data was transferred to ReDIM software to analyze the drought period for 3 and 12 months periods by using the SPI and RUN methods. As a result of SPI analysis performed for the three months period; the most severe drought was observed between May 1989 and October 1989. The longest period of drought was observed between September 1972 and March 1975. For the twelve months period; the most severe drought was observed in the period between May 2001 and April 2002. The longest drought was found between April 1972 and April 1975. According to the RUN method; the longest drought was occurred between 2003 and 2008. The highest cumulative water deficiency was 42551 m3 between 1970 and 1974, and the maximum drought intensity was 10859 m3 in 1994. Moreover, hydrological droughts that have 4 years or more duration occurs in every 20 years in the basin. Water resources in this region must be protected due to there is a drought risk between years of 2020-2023
