Lake Rweru (Burundi)

Weather…

Lake Rweru is a major freshwater lake located in the far north of Burundi, right on the border with Rwanda. It is geographically significant because the Kagera River, a major source of the Nile, flows through the lake or touches its northern extremity. Covering an area of approximately 100 square kilometers, it is the largest of the northern Burundian lakes and serves as a critical reservoir for the region's biodiversity. Historically, the lake was a hub for trade between the kingdoms of Burundi and Rwanda and continues to be a vital source for local fisheries, particularly for Tilapia. The shores are lined with dense papyrus marshes that create a labyrinth of waterways, providing sanctuary for numerous endangered species. However, the lake faces ecological pressure from overfishing and the spread of water hyacinth, which can cover large portions of its surface. Preserving Lake Rweru is essential for local climate stability and the water security of the surrounding provinces.
