The species is known from Lakes Vierwaldstätter (102 km²), and possibly also Alpnach (3 km²) and Sarnen (7 km²) and was extirpated from Lake Zug (31 km²) before 1950. The species is very abundant in Lake Vierwaldstätter where there is no known current or future threat. There is also no potential threat from introduced species due to the strict management of the Swiss lakes.
