Means of Introduction: Unknown. According to Logan (personal communication), Oregon introductions took place during the 1920s.
Status: Introductions into Paulina and East lakes in Oregon were unsuccessful (Logan, personal communication). Status of Diamond Lake introduction unknown.
Impact of Introduction: The impacts of this species are currently unknown, as no studies have been done to determine how it has affected ecosystems in the invaded range. The absence of data does not equate to lack of effects. It does, however, mean that research is required to evaluate effects before conclusions can be made.
