translate English to French: Only when excess water collects in the cistern or it is too cool to be used in the bathing pool, is water allowed to flow on the surface above Mountain Avenue before joining used, chlorinated, pool water and surfacing once again below Mountain Avenue into the outflow stream.
L’existence de cette citerne est même mentionnée dans un guide récent sur les sources thermales de l’Ouest canadien (Woodsworth, 1999).
