Medlow Dam, Medlow Bath
Today, it still supplies water to the middle and upper Blue Mountains. The dam is not open to the public.
Originally known as Adams Creek Dam, Lake Medlow Dam and Medlow Bath Reservoir was built in 1907 on Adams Creek. It was the first of the water supply dams built as part of the development of the Upper Blue Mountains.
It was the first concrete thin arch, high-stress dam built in NSW. Only 274 centimetres wide at the bottom and 106 centimetres at the top, it is one of the thinnest dams in the world and created considerable controversy when it was completed.
The Institution of Engineers, Australia placed a historic engineering marker on the dam in 1994. The National Trust and Blue Mountains City Council have registered the dam on their heritage list.
