The Hassel Auxiliary Dam or Hassel Dam (German: Hasselvorsperre or Vorsperre Hassel) is an auxiliary dam or pre-dam on the Rappbode Reservoir in the Harz mountains of central Germany. It is located near Hasselfelde in the state of Saxony-Anhalt and impounds the waters of the Hassel, the eastern of the two headwaters of the Rappbode Reservoir. Together with its auxiliary dams, the reservoir supplies drinking water and is owned by the Saxony-Anhalt Dam Company (Talsperrenbetrieb Sachsen-Anhalt). The purpose of the auxiliary dam is to pre-clean water mechanically and biologically before it flows into the main reservoir. Water can be collected from various heights and diverted to the reservoir. The barrier itself is a 21 m high gravity dam. The bedrock consists mostly of grauwacke, but with some thinly laminated argillaceous shale as well. There is a circular path around the Hassel Auxiliary Dam. The crest of the dam is accessible to pedestrians and the lake may be fished provided permission is obtained. The Hassel Auxiliary Dam is checkpoint no. 53 in the Harzer Wandernadel hiking trail network.

Oberharz am Brocken (German pronunciation: [ˌoːbɐhaːɐ̯ts ʔam ˈbʁɔkŋ̍]) is a town in the Harz District, in Saxony-Anhalt, Germany. It was formed on 1 January 2010 by the merger of the town of Elbingerode with the municipalities of the former Verwaltungsgemeinschaft ("collective municipality") Brocken-Hochharz (except for Allrode).The name chosen by the new town's administration has caused some disturbance, as the area is not part of the Upper Harz region, which traditionally refers to the seven mining towns (Bergstädte) of Clausthal, Zellerfeld, Andreasberg, Altenau, Lautenthal, Wildemann, and Grund, all located in the neighbouring state of Lower Saxony. A lawsuit filed by the Lower Saxon Samtgemeinde ("collective municipality") Oberharz in 2009 was dismissed by the Saxony-Anhalt administrative court in Magdeburg.
