In the UK, and more precisely, in Wales, there is perhaps the most beautiful dam in the world - Craig Goch. This dam separates Kronfa Ddur Craig Gok and Penigarreg Reservoir. It was built, of course, to form a reservoir, one of the purposes of which is to provide Birmingham with water. Construction of the dam began in 1897, and was completed fairly quickly for such a large-scale project - in 1904. In 1997, a hydroelectric generator began to work on the dam.Solid areas: 1%
