The Saidenbach Dam is a dam in Saxony. It supplies drinking water to Chemnitz and, in conjunction with the "Middle Ore Mountains" dam system, as well as the Neunzehnhain I and II and Einsiedel dams, to the entire supply area of the Southern Saxony Long-Distance Water Association.
The dam wall of the Saidenbach Dam is a curved gravity dam made of quarry stone masonry based on the Intze principle. The dam was built between 1929 and 1933 near Lengefeld in the Ore Mountains (commissioned in 1933). It is a "large dam" according to ICOLD criteria. The dammed waters are the Haselbach, Saidenbach, Lippersdorfer Bach and Hölzelbergbach.
A public path leads over the dam wall. Swimming and recreational sports are not possible in the reservoir, but you can hike and fish around the reservoir.
