of Campbell Island

Campbell Island has 14 named streams and many more unnamed waterways. The island also supports many tarns, some of which are permanent water bodies, as well as countless seepages.

Many of the island’s tarns are exposed to wind-blown salt spray (with salinities up to 4810 μS/cm), which may have an influence on aquatic assemblages.

The streams range from fast-flowing cobble-bed streams, to slower flowing peat channels that sometimes go underground.

The water is tannin-stained, with acidic to neutral pH, well oxygenated with cool summer water temperatures (7.4–10.8 °C). Riparian vegetation is either dominated by Dracophyllum, tussocks, or a mixture of these and ferns.
