The Engineering Marvel: Isel Dam

The Isel Reservoir is a testament to early 20th-century engineering, primarily serving as a crucial source for electricity generation in Arosa. Originally constructed between 1895 and 1896, it underwent significant expansion in 1982 when its height was raised by 12 meters with a new dam wall. This impressive structure not only holds back the vast body of water but also plays a role in water management, with the old dam sometimes serving as a retention wall during maintenance work on the new one.

Visitors can appreciate the scale and design of the dam, which is integrated into the natural mountain landscape. It's a fascinating point of interest for those who appreciate industrial history and its impact on the region's development. The sheer size of the dam is often a point of discussion among visitors, highlighting the human effort involved in harnessing natural resources.

While the dam is functional, its presence creates a dramatic backdrop for the otherwise serene reservoir. It's a reminder of the dual nature of the reserve – a place of natural beauty and a site of important infrastructure.
