Assessment Summary – November 2003
Common name: Rocky Mountain Ridged Mussel
Scientific name: Gonidea angulata
Status: Special Concern
Reason for designation: The distribution of this species is limited to southern British Columbia in the Okanagan and Kootenay River systems. This species has likely been impacted by the damming of the Kootenay, Columbia and Okanagan Rivers and the channelization of the Okanagan River and resulted in loss of alteration of the mussel's habitat quality and extent.
Occurrence: British Columbia
Status history: Designated Special Concern in November 2003. Assessment based on a new status report.
