Distribution of Sphaerium simile in British Columbia
Details about map content are available here.


Sphaerium simile is found throughout southern Canada (Clarke, 1981), and southwards into the United States but apparently not extending south of the area covered by the glaciers (Herrington, 1962). It is found in southern British Columbia.

A common species (Clarke, 1981), with the largest populations seeming to occur on depositional substrates in lakes and eddies of permanent rivers and creeks. In lakes, the substrate is usually mud or sand, or both, and submersed vegetation is usually common. In creeks and rivers, the substrate is often thick organic ooze and vegetation may or may not be present (Mackie, 2007).
