The construction of hydroelectric power plants to develop electricity sources is one of the critical factors of the economic development in Kon Tum Province. Investing in the construction of hydroelectric work contributes to the national electricity source. It also actively contributes to the local irrigation by providing water in the dry season and reducing floods in the wet season. Dak Bla Thuong hydropower plant is in line with the master plan of the Dak Bla river basin, and will optimally exploit energy for the planned river section without affecting neighboring systems in the Dak Po Co river system. Besides, it will contribute to adding a significant energy source to the national power system with a total installed capacity of 9.0 MW and an annual electricity output of about Eo = 31.85 million KW. This paper used a purely statistical method based on a series of hydrological data from 1977 to 2019 to calculate some hydrological features such as standard volumetric flow rate, the minimum monthly flow, the design of flood discharge maximum, etc to serve the licensing of exploitation and use of surface water, ensuring that the work implements well the task of generating electricity while ensuring the minimum flow to the downstream to diminish the risk which is caused by the operation process of electricity generation.
