## Abstract
This study aims to assess water availability in the Kelekar River Basin. Various water resource issues are increasingly complex, driven by increasing water demand in line with population growth and socio-economic growth. Furthermore, mismanagement of water resources has led to overexploitation of water resources, resulting in a decline in the environmental carrying capacity of water resources, which in turn reduces water supply capacity. The NRECA model and SWAT+ application is used as mathematical model for rainfall-runoff simulation. From the discharge modeling results obtained, a reliable discharge can be determined as a basis for determining the service area to be irrigated. Result of study is the reliability of discharge in the Kelekar River Ogan Ilir Basin for the 50% dependable discharge (Q 50 ) is a maximum of 350 m 3 /sec while for the 80% dependable discharge (Q 80 ) it is 255 m 3 /sec. It is quite ideal to fulfill water availability with a watershed area of 2463.61 km 2 and the Q 80 dependable flow is small enough to meet raw water and irrigation water needs. Under actual conditions, the raw water value could be reduced, given that irrigation must continue. This could also be achieved by constructing a reservoir to store water during surplus months and releasing it during months with a water deficit.
