"Muskrat Creek is a small tributary of the Teeswater River (Lake Huron drainage) in southwestern Ontario. In 2005, a live Truncilla donaciformis (Fawnsfoot) was found in Muskrat Creek representing the first detection of this endangered species in the Lake Huron drainage outside of its known range in the Lake Erie and Lake St. Clair drainages. Muskrat Creek is considered a current location of T. donaciformis by the Committee on the Status of Endangered Wildlife in Canada. In 2019, Fisheries and Oceans Canada completed timed-search surveys and quadrat excavation in Muskrat Creek and the Teeswater River to investigate the presence of T. donaciformis in the survey area and determine if this is still a current location for this species. No evidence of T. donaciformis was detected in either waterbody and no live unionids were detected in Muskrat Creek. Based on the search effort completed, the probability of detecting at least one T. donaciformis individual was >99.9% for the timed-search surveys and 96% – >99.9% for the quadrat surveys. The lack of evidence despite a high probability of detection indicates that Muskrat Creek is unlikely to support a viable population of T. donaciformis"--Abstract, page v.
