Resilience (m) often used to characterize reservoirs as within or over year systems describes how quickly a system is likely to recover from failure. This study characterize the Kainji reservoir system adopting Vogel stedinger relationship on reservoir resilience and boundary conditions. Inflows data between 1990 2014 obtained from Kainji Dam hydrological station were used in characterizing the reservoir system. The demand levels were hypothetically fixed at 0, 0.2, 0.4, 0.6 and 0.8 in line with reservoir boundary conditions (i.e. if 0≤m≤1, the reservoir system is dominated by over year behavior, whereas if m >1) the system is dominated by within year behavior). The result obtained showed that all the values obtained for resilience m were above one except the demand level of 0.8 with 0.8 resilience value which can be approximated to one. The coefficient of variation was also low, on the basis of this the reservoir was characterize as within year system. The resilience indices m increases with reduction in the demand level which depicts that the higher the demand level the less the reservoir resilience.
