General Description
See (Clarke 1981) for general description.

Range Comments
Known originally from western Montana, and currently may be found in northwest Montana kettle lakes that are undisturbed; exact extent unknown (Frest and Johannes 1995).

Migration
Sedentary.

Threats or Limiting Factors
According to (Frest and Johannes 1995), the species faces ongoing major threats and a very substantial reduction in habitat; species is not found in strongly eutropified kettle lakes, nor in streams; lakes used as part of irrigation systems, with untreated sewage, or having other sources of nutrient enrichment, seem to lack the species; lakes with extensive treatment to kill out aquatic macrophytes or to stock or modify the native fish fauna also seem to lack this species (Frest and Johannes 1995).
