Das Wiedererwachen des Lüschersees

Discharge of the lake in 1910
Because at that time a connection between the Lüschersee and the landslides on the Heinzenberg was suspected, the lake was drained by an artificial tunnel (Fig. 2 & 3).

2018 to 2021
Extensive geological and hydrological investigations have shown that the Lüschersee has only a minor influence on the landslides on the Heinzenberg (Fig. 4).

Reactivation and use of the lake from 2022
Winter and summer tourism is now to be promoted through the reactivation of Lake Lüschersee. The water of the lake is used in the first winter months for technical snowmaking.

Change in biodiversity
On the territory of the former lake, after emptying, new small bodies of water and moor have formed areas on which 9 different dragonfly species (Fig. 5) have been detected. In order to preserve this biodiversity, the loss of small areas worthy of protection is compensated by local replacement measures in Fig. 6 & 7.
