Obermaubach Reservoir

This diverse reservoir is recommended at any time of year. It and its surroundings also have a lot to offer for children.
The fish ladder with the glass underwater area is definitely recommended for children. Here you can watch the fish (as they swim past) like in an aquarium.

When the construction of the Urft dam began in 1900, no one could have known that it was also a decision to build the Obermaubach reservoir. The reservoir and the Urft dam are closely interwoven.
The Rurthalsperrengesellschaft, which was founded to build the dam at Urft, had decided to finance the project, Heimbach a power plant - the "Art Nouveau power plant" - to build, which should be won electricity from hydropower. Through a tunnel through the Kermeter and a subsequent pressure line water from the Urftsee was steered with a steep slope on the turbines. Electricity as a young form of energy was a growth market during this time, and so the power plant was able to work in continuous operation.
