There is no raal tributary to the lake and the outflow will disappear in the underground after some distance as the area consists of landslide debris. The area of the landslide can easily be spotted from the Disentis direction.

Several hiking paths or mountainbike routes lead to the area. Some people swim on hot summer days although water temperature is less than 17 degrees Celsius. In the bottom of the valley a multiday hike[1] leads along the river Rhine.
