Neuer Grumbacher Teich, Water reservoir in Goslar, Germany.
Neuer Grumbacher Teich sits behind an earthen dam in the forested highlands above Goslar, holding dark water surrounded by spruce and beech trees. The reservoir basin stretches between gentle slopes, with its surface reflecting the surrounding woodland canopy throughout the year.
The basin was created in 1714 as part of a larger waterway system that powered mines throughout the Harz region. For over two centuries, the reservoir fed waterwheels and pumps before mining operations declined in the 19th century.
The reservoir stands as a testament to German engineering excellence, demonstrating historical water management techniques that supported regional mining activities.
Hiking trails lead through the forest to the dam and along the shore, with the climb from the valley taking roughly an hour. Sturdy footwear helps on sections that can become slippery after rain, especially where roots cross the path.
The basin belongs to a network of over 60 historic ponds now recognized together as a World Heritage site. Birds nest along the quiet shoreline while water still flows through old channels to neighboring reservoirs.
