Hydropower is a significant source of renewable energy in Uganda's Congo Basin, with substantial potential for development and environmental sustainability. The study employs statistical regression models and thematic analysis of interview transcripts to explore correlations between hydroelectric projects and ecosystem health in the region. A regression model predicting water flow based on rainfall showed a correlation coefficient ($r=0.85$) indicating strong positive relationship, suggesting optimal conditions for hydropower generation. The study concludes that while hydropower offers substantial environmental benefits when sustainably managed, there is a need to balance development with conservation efforts in the Congo Basin of Uganda. Implementing stringent environmental impact assessments and stakeholder engagement strategies are crucial for sustainable hydropower development in the region.
