The reservoir has a water surface area of approximately 1.1 square kilometers.
The dam wall reaches a height of 78 meters above its foundation.
The site operates as a pump storage power plant, using excess electricity to pump water into the reservoir.
The cable car was originally constructed primarily to support the transport of building materials for the dam project in the late 1950s.
Lünersee was once considered one of the largest natural alpine lakes in the Eastern Alps before the damming project significantly increased its volume.
The reservoir can store up to 76 million cubic meters of water.
The area is a recognized habitat for alpine flora, including protected species like edelweiss and gentian.
The Lünerseebahn is a high-altitude aerial tramway that transports passengers from the floor of the Brandnertal valley at 1,567 meters to the Lünersee reservoir at 1,979 meters. The cable car system overcomes a 412-meter vertical rise in approximately five minutes. The reservoir serves as both a hydroelectric storage facility for the Vorarlberg Illwerke group and a central hub for alpine hiking in the Rätikon mountain range. The lake, historically a natural alpine tarn, was dammed to its current capacity in the 1950s. The site serves as a base for high-altitude trekking toward the Schesaplana, the highest peak in the Rätikon Alps. Infrastructure at the top station includes a mountain restaurant and direct access to the circular lake trail.
The dam wall crest offers the most expansive panoramic view of the lake surface and the surrounding peaks.
Check mountain weather forecasts specifically for the Rätikon region before departing, as conditions at 2,000 meters shift rapidly.
Bring layers, as temperatures near the reservoir are significantly lower than in the Brand valley.
The circular trail around the lake is relatively flat, but requires sturdy hiking boots due to uneven rock terrain.
Attempting to hike to the Schesaplana peak without adequate alpine experience or proper weather gear.
Operates exclusively during the summer and early autumn season; closed during winter months due to avalanche risk and heavy snow accumulation.
Hikers should remain on marked paths to protect alpine meadows and avoid disturbing grazing livestock.
