||Water, as we all know, makes life possible on Earth. Thus, the accessibility and availability of water sources have historically decided the rise and fall of civilizations around the world.
Scientific research has shown that the Kathmandu Valley once contained a great lake, and it only became habitable once the lake was drained. Buddhist narratives place the agency behind the draining with Manjushri, while later Hindu accounts place it with Krishna (Slusser, 1982). The fertile alluvial soil present in the valley adds to the argument of the valley once being a lake. In addition, there are many water sources in the valley, including rivers, small lakes, ponds, wetlands, wells, springs, and stone waterspouts.
