Blagdon Lake lies in a valley at the northern edge of the
Mendip Hills, close to the village of
Blagdon and approximately south of
Bristol, England. The lake was created by
Bristol Water (Bristol Waterworks Company as it was known then), when it dammed the
River Yeo, starting construction in 1898, to designs by
Charles Hawksley, and completing this in 1905. The
Wrington Vale Light Railway was constructed primarily to bring building materials for the lake.
