The Huttaler Widerwaage is a small reservoir that is a part of the Upper Harz Water Regale, an old mining water management system in the Harz Mountains of Germany that is now a UNESCO World Heritage Site. The reservoir lies east of the mining town of Clausthal-Zellerfeld. It is designed to feed water from the Huttal river during times of low water to the reservoir pond of the Hirschler Teich and, during times of high water, to handle the overflow of water from it.
