Lake Mattmark, Alpine reservoir in Saas-Almagell, Switzerland.
The Mattmark reservoir spans across the Saas Valley at 2143 meters elevation, featuring Europe's largest earth dam for hydroelectric power generation.
The construction of Lake Mattmark in the mid-20th century transformed the region into a major source of renewable energy through glacial meltwater collection.
The reservoir attracts numerous outdoor enthusiasts who participate in hiking activities along the 7.9-kilometer trail circling the water body.
The circular path around Lake Mattmark takes approximately two and a half hours to complete, with minimal elevation changes of 137 meters.
The reservoir's information center, located within the restaurant building, presents detailed exhibits about the power plant's construction and operations.
