Sinfonia d’aua in Flims

30 January 2019

Sinfonia d’aua in Flims consists of six small hydropower plants. It shows how nature, technology and people interact and function.

The project encompasses natural phenomena and systems, ecological electricity production, sustainable water use, and multifunctional infrastructure for snowmaking.

For thousands of years, the water in the limestone has sought new ways and created a widely branched underground system.

The two largest lakes in Flims, Lake Cauma and Lake Cresta, are fed by underground sources. Lake Cauma also lacks above-ground drainage, and the water level fluctuates by up to seven metres per year.

It is a groundwater lake. The light scattering creates the natural turquoise blue on small inorganic suspended particles. The unique colour and idyllic location make Lake Cauma world-famous. Point Gronda is the visitor centre.
