Laute is a river of Lower Saxony, Germany. It is a right tributary of the Innerste. The Laute rises in the vicinity of Hahnenklee in the Upper Harz and discharges about 6 km (3.7 mi) later into the Innerste in Lautenthal. The source is at an elevation of about 540 m at the bottom of a mountain called Kuttelbacher Berg. The Laute flows to the west parallel to road L 516 which is called Hahnenkleer Straße in Lautenthal. The name of the town means Laute Valley. The mouth is at an elevation of about 300 m in the west of Wildemanner Strasse, the high street of Lautenthal. In 1875 a railway bridge of the Innerste Valley Railway was built over the Laute close to its mouth. Although the railway line was closed in 1977, the bridge is well preserved and still used by hikers. A flood of the Laute caused considerable damage in Lautenthal in 1877.

The Lower Grumbach Pond (German: Unterer Grumbacher Teich), usually just Grumbach Pond (Grumbacher Teich), is an old mining reservoir or Kunstteich between Hahnenklee and Wildemann in the Upper Harz mountains in Germany It is one of the Upper Harz Ponds and was constructed before 1673. After being raised in height at least once, the dam today is 7.5 metres high and just under 60 metres long. There are nine other ponds within its catchment area, all part of the Upper Harz Water Regale: the Kranicher Teichen, the Kuttelbacher Teich, the Auerhahnteich, the Upper (Oberer) and Middle (Mittlerer) Grumbach Ponds and the Upper and Lower (Oberer and Unterer) Flößteich. Its catchment area is 7.92 km² which is very large for an Upper Harz Pond and results in a high volumetric flow. Its impoundment capacity is 82,000 m³.The pond was not only used for generating hydropower for the pits beneath, but also played an important role in timber rafting on the Grumbach stream to Wildemann. The timber, cut into one to two metre-long logs, was led by a rafting ditch around the pond and slid down the Gefluder in the present day Grumbach Waterfall into the stream. In order to transport the wood further downstream, water was periodically released from the Lower Grumbach Pond which ferried the logs down to the River Innerste.By the Lower Grumbach Pond is a refuge hut with checkpoint no. 113 "Grumbacher Teich" on the Harzer Wandernadel hiking network.
