One deck below the Hurricane Deck and SO much water! I love how rainbows just appear at different times and places in the falls.
This picture was taken from the Canadian side of the falls looking at the American Falls. You can see the Maid of the Mis boat in the water and also the beautiful Rainbow Bridge across the Niagara Gorge.
The volume of water going over the falls is amazing. And to think that it is 50% less than what naturally flows across due to volumes of water taken for power production. At night an additional 25% of the flow is taken from the Niagara River and sent in underground tunnels 7 miles downstream to the power plant and then returned to the flow of the river headed to the Atlantic Ocean.
