to walkers and mountain bikers. Access to the dam wall and lake is still prohibited. Originally envisaged to supply steam trains, Woodford Dam is one of six dams constructed to supply water to the Blue Mountains area. Two raisings have occurred with the latest in 1947. Due to the closure of the Linden Water filtration Plant in circa 2000, the storage is no longer used for water supply and the outlet raw water pipework has been disconnected and capped. The first stage was constructed by NSW Railways between 1928 and 1929. Stage two raised the storage by 2.44m in 1935. The final third stage increased the storage by an additional 3.05m in 1947. Although rare, the storage has been used for rural firefighting by helicopters. The dam wall is an arch/gravity structure with keyed vertical contraction joints and copper waterstops. The foundations are excavated into the sandstone in a series of steps References Coordinates - Lake Medlow Dam - Greaves Creek Dam - Upper Cascade Dam - Middle Cascade Dam - Lower Cascade Dam - Woodford Dam External links Blue Mountains Dams at WaterNSW.
