Gyraulus crenophilus is restricted to the lake and three feeder springs in the Lake Ohrid water catchment, and is assessed as Endangered B1ab(iii). The total EOO is no more than 500 km2, it lives at low densities and pollution is causing a decline in water quality, which impacts the habitats and feeding areas of this species, which requires clean water and is intolerant of pollution.

It is found at suitable habitats in low abundances.
|Current Population Trend:||Unknown|
|Habitat and Ecology:||This species is restricted to the littoral zone of the lake with sublacustrine springs and cold water springs. It is probably a species needing a specific (and narrow) constant water temperature and chemistry (C. Albrecht pers. comm. 2009).|
|Continuing decline in area, extent and/or quality of habitat:||Yes|
Pollution from sewage from major cities adjacent to the lake is contaminating the water of the lake. Increasing sediment load (due to construction of new settlements, deforestation and erosion of the neighbouring area) also impacts this gastropod. Agriculture near the Prespa Lake are contaminating the
There are no conservation actions in place for this species. More sustainable water management is needed to ensure the continuing quality of the habitat. Monitoring habitat trends would be beneficial for this species.
