This case study examines the impacts of climate change on water resources at Lake Powell, USA, using a comprehensive methodology combining data analysis through regression and system dynamics modeling. Through regression analysis, historical data is analyzed to identify trends and relationships between climate change factors and their impact on water resources. A system dynamics model is then used to simulate reservoir dynamics illustrating the effects of inflow and outflow on water reservoir depletion. The results from both methods reveal the challenges of current water management regulations and policies to address the risks posed by climate change at Lake Powell. Therefore, this case study highlights the urgent need for sustainable water management policies at Lake Powell. Underscoring the seriousness of the problem overhaul of existing strategies, the research argues for proactive measures to mitigate the effects of climate change. The study provides policymakers and water resource agencies with significant insights and recommendations sustainable utilization of this essential resource.
