Abstract: The management and operation of water reservoirs particularly in regions susceptible to climate change and inadequate resource utilization requires careful consideration. This research focuses on the Alau dam situated in Northern Nigeria, a critical water source for the region. Despite its significance, the dam's performance faces challenges such as sedimentation, flooding, and insufficient adaptation to climate change. This study investigates the current state of management and operations at the Alau dam's reservoir emphasizing the frequency, challenges, and existing strategies. Utilizing a mixed-methods approach, including interviews, field observations, and analysis of water quality and water level, and aerial imagery. The study investigates the impact of these factors on the dam’s capacity, functionality, and structural integrity. Over time, sediment deposition has substantially reduced the reservoir’s effective storage capacity, leading to a misleading increase in surface area without corresponding water volume, thereby heightening the risk of overtopping and structural failure. Additionally, delayed and inflexible water release practices have exacerbated downstream flooding, while placing excessive hydraulic pressure on the dam's infrastructure, particularly the earthen embankments. The absence of a sediment management plan, coupled with inadequate maintenance, has further compromised the dam’s operational effectiveness and increased the likelihood of catastrophic failure. This study highlights the need for a shift toward adaptive management practices, including sediment removal, regular maintenance, real-time monitoring, and the incorporation of environmental flows. Recommendations include the implementation of a data-driven water release policy, infrastructure upgrades, secondary storage systems, and enhanced stakeholder engagement. These measures are critical for reducing flood risks, preserving downstream ecosystems, and ensuring the long-term sustainability and safety of the Alau Dam.
