Wapama Falls is the larger of two waterfalls located on the northern wall of Hetch Hetchy Valley in Yosemite National Park. Arguably the most powerful waterfall in Yosemite National Park, it flows almost year-round and during peak flow has been known to inundate the trail bridge crossing it, making the falls impossible to pass during peak flow. The falls consist of two primary drops angled roughly 60 degrees to each other, and a broad cascade at its base.
