Huge dam spillways

Huge dam spillways:
I already discussed the biggest dam spillway in the world on this blog ( The spillway of the Robert Bourassa dam in canada ). These dam spillways are generally used to release the water from the water bassins behind a dam in case of a flood. These things are most of the time build in the construction of the dam itself like for example in the Itaipu dam in Paraguay which is one the biggest spillways ( 500 meters long and 350 meters wide) in the world in terms of water capacity. When water is released from this thing it makes a hell of a noise:



The biggest kind of spillways however can be found at earthfilled dams situated next to the dam instead in the structure of the dam itself. Like for example this huge spillway at the W.A.C Bennet dam in Canada:




It is 800 meters long and about 35 meters wide. Another huge one is this one at the Garrison Dam in North Dakota in the U.S. It is part of one of the world's largest earth filled dams which forms the Sakakawea Reservoir on the Missouri River. The spillway itself is 800 meters long and is almost 350 meters wide at the point where the water enters the spillway:



The most impressive and biggest concrete spillway in the world however is the spillway which is part of Fort Peck Lake dam in Montana in the U.S. The dam itself is the largest earth-filled dam in the world. The spillway is 1500 meters long and 150 meters wide:






Another earth filled dam ( which is also among the biggest earthfilled dams in the world) with impressive spillways is the Tarbela dam in Pakistan. This dam actually has 2 giant spillways. One of them has a lenght of 780 meters and a wide of 100 meters and the other one has a length of about 200 meters and a wide of 150 meters:





Another huge one is the spillway which is part of the Nagarjuna sagar dam in India. The spillway is build in the dam itself and is 500 meters wide:




And last but not least the giant dam spillway of the Ataturk dam in Turkey. This thing is 900 meters long and 150 meters wide:
