The dam wall reaches a height of 65 meters above the foundation.
The reservoir holds approximately 14.4 million cubic meters of water at full capacity.
It is a key component of the Murg Valley's complex hydroelectric infrastructure.
The project was a pioneer in regional pumped storage technology during the 1920s.
The dam structure is built of granite blocks sourced from local quarries.
Schwarzenbach Dam is the largest reservoir in the northern Black Forest, spanning approximately 2.5 kilometers in length. The gravity dam was constructed between 1922 and 1926 to support hydroelectric power generation. The reservoir is part of the Rudolf-Fettweis-Werk pumped storage power plant system. Visitors can access a dedicated boat rental station to explore the water surface. The surrounding topography features steep, forested slopes typical of the Murg Valley region. Water levels fluctuate depending on energy production requirements and seasonal rainfall. A circular hiking trail surrounds the reservoir, offering views from multiple elevations.
The crest of the dam wall provides the most expansive panoramic view of the water and the surrounding forest.
Carry insect repellent if walking the perimeter trails during summer months.
Verify water-based activity availability in advance, as levels vary based on energy demand.
Wear sturdy footwear if planning to hike the full loop around the reservoir.
Do not attempt to swim in the reservoir, as it is a working power facility with fluctuating currents and cold temperatures.
Boat rentals operate seasonally from spring through autumn and are weather-dependent; the dam area itself is accessible year-round.
Maintain noise levels near the shoreline; swimming is generally restricted due to the dam's function as a power reservoir.
