00:00Why would anyone deliberately reduce the water flowing over Niagara Falls?
00:04Since November 1st, the minimum required flow has dropped by half for the winter season.
00:09Instead of requiring 100,000 cubic feet of water per second,
00:13the rules now allow a minimum of 50,000.
00:16But this water isn't simply disappearing.
00:19Much of the river's flow can be redirected through channels and tunnels
00:22toward hydroelectric power stations in the United States and Canada.
00:26There, powerful turbines use moving water to generate electricity
00:31before releasing it back into the Niagara River downstream.
00:35This system operates under a 1950 agreement between the two countries,
00:39balancing electricity production with the waterfall's natural beauty.
00:43And humans have gone even further.
00:45Back in 1969, engineers temporarily stopped the flow over the American Falls
00:51to investigate erosion and rock stability.
00:54The waterfall continued flowing nearby,
00:56but the American side revealed a remarkable sight,
00:59its normally hidden rock face.
