The pictures illustrate a number of important changes which took place in a town after the construction of a hydroelectric power dam.
From the maps, it is clear that the most noticeable change that occurred in the town was that of a huge lake. Additionally, the forest and farmlands had completely disappeared by 2010.
In 1990, there was an ancient structure and a forest with rare flora and fauna to the west of the river, and irrigated farmlands to the east. However, with the construction of a dam wall, those features disappeared beneath a large lake, which also became a fishing area in 2010.
Looking at the maps in more detail, while the mountains still existed, the villages in the far east were relocated further south of the mountains, and a large hotel was built in their place. Meanwhile, a hydroelectric power dam was constructed with a wide range of electricity .
