The Inguri Dam (Ingurskaya) is a hydroelectric dam on the Inguri River in Georgia. The dam was completed in 1984, and at 270 m, it is one of the world's tallest dams.|
The Grande Dixence dam, at the head of the Val d'Hérens in the canton of Valais in Switzerland, is at 285 metres high one of the world's tallest dams. It holds back a lake, the Lac des Dix, around 16 km long.

This is a Dam good site.
The question is somewhat ambiguous describing the Grand Coulee but calling it the world's largest. It is not. It once was, but no longer.
The Three Gorges Dam is the largest hydropower
station and dam in the world, with a 1.2 mile stretch of concrete. As planned, the capacity of Three Gorges Dam, 17 million kilowatts, will top that of the largest dam currently operating by 40 percent. Its projected annual power generation of 84 billion kilowatt-hours is equivalent to a coal mine capacity of 40 to 50 million tons per year. The project will supply power mainly to the central China grid of Hubei, Hunan, Henen, and Jiangsu, and Anhui. It will cost (in 1990 prices) as estimated RMB 57 billion ($ 10.57 billion). Once completed, the dam will be 185 meters high and store 39.3 billion cubic meters of water. It will create a reservoir 36 miles long and 525 feet deep.
