Suddenly the dam began to move, at first slowly.

The dam began construction in 1974, and the project was completed in 2004.

This dam began as a natural outcropping in the riverbed.

Around midnight on October 8 the dam began to give way.

The dam and powerhouse first began to delivery electricity on February 12, 1926.

As the dams began to fill, downstream water flow decreased significantly.

On 24 February 2012, the dam was complete and began to impound its reservoir.

After a few days, the entire dam suddenly began to shake violently.

The dam was complete and began to impound water in 2008.

The dam began to disintegrate, though, in the early 1960s.
