In the continuous permafrost zone, unfrozen ground may exist beneath large lakes and streams. Sub‐lake taliks that extend through permafrost provide a potential conduit for subpermafrost groundwater to reach the surface, increasing dissolved ion concentrations in lake water. Twenty‐eight lakes on th...
