The species is only known from four lakes in Cumbria, UK. Haweswater (3 km²), Ullswater (14 km²), Brotherswater (<0.5 km²) and Red Tarn (<0.5 km²). The population has strongly declined in Hawswater (17% of its total range) which is still ongoing, due to water abstraction and cormorant predation. The area of occupancy of the species is around 20 km².
