The Elan Valley dams
|Changing the landscape
James Mansergh's detailed report on the area upon which the huge project was based included an impressive scale relief model of the watershed of the rivers Elan and Claerwen which he had built with the help of his son.

The model is of particular interest in that it included the
three dams originally proposed for the Claerwen Valley, seen
extending to the left. Of these, only the base of the dam at
Dol-y-Mynach (bottom right of
the model above) was destined to be built. The valley of
the River Elan runs vertically on the right of the model, and
the reservoirs shown were all created by the scheme.
Another view of the Elan Valley taken from an early
souvenir postcard is shown (right), with the picture captioned
"Before Waterworks Scheme".
