This slideshow provides information about the Waikato River in New Zealand. It is 425 km long, starting at Lake Taupo and flowing to Port Waikato, becoming increasingly polluted along its path through farms and cities. The river is owned by the Tainui iwi, requiring their permission for any construction. It is home to various fish species and used for hydro power, swimming, canoeing, kayaking and fishing.
