We report a population of the mussel the black sandshell (Ligurnia recta [Lamarck, 1819]) from the Carrot River in Saskatchewan, far north of the species' known range in southern Manitoba and northwestern Ontario. Ligumia recta is reported to be declining substantially in its abundance and range, and this occurrence provides valuable information for the construction of a species status report in Canada.
