The Neustadt Dam, also known as the Nordhausen Dam (German: Talsperre Neustadt or Nordhäuser Talsperre) is the oldest dam in the Free State of Thuringia in Germany. It supplies drinking water to the town of Nordhausen. The dam is a curved gravity dam made of rubble stone based on the Intze Principle. The dam was built in 1904–1905 in the southern Harz mountains and raised by a further 6.26 metres in 1922–1923. The impounded stream is the Krebsbach. The operator of the dam is the Thüringer Fernwasserversorgung; the water is supplied to the Wasserverband Nordhausen (Nordhausen Water Association).
Swimming and water sports are not permitted on the lake, but there is a public path around the lakeshore.
The dam was refurbished between 1997 and 2001. It was reinforced, waterproofed on the upstream side with asphaltic concrete, given an inspection walkway and an impervious blanket.
On the western side of the valley is a checkpoint (no. 218) in the Harzer Wandernadel hiking system.
