Patea River
The Patea River originates on Taranaki Maunga and flows east of the mountain through Stratford. To the south-east of the town, the Patea is joined by the Mangaehu River, its largest tributary, which drains eastern hill country. The Patea then gradually heads south and passes through Lake Rotorangi and the Patea hydroelectric power scheme before entering the sea at Patea. The Patea River holds special value for Ngāti Ruanui and Ngaa Rauru Kiitahi Iwi.
Ecological health in the catchment is stable. Water quality is expected to improve in coming years as new riparian fencing and planting in the catchment becomes established.
Including Te Papakura o Taranaki, the Patea catchment has a total of 5,323 km of stream bank. Many of the tributaries headwaters within the Patea catchment are in the Eastern Hill country where much of the streambank is protected by natural vegetation. The exact length of stream bank protected by riparian vegetation in this area has not been calculated and is not included in the current figures provided below for the extent of riparian vegetation. Therefore, the current figures do not represent the total amount of riparian vegetation in the Patea catchment.
The Council’s database shows 18% of the stream banks in the Patea catchment are planted in riparian vegetation with 1% stream banks located within Te Papakura o Taranaki and 17% of stream banks covered by a Council riparian management plan outside the park boundary. Further to this, 1% of stream banks are protected by riparian fencing within the National Park while a further 32% of stream banks are fenced outside the park. There are stretches of stream bank that are both fenced and planted.
Overall, 34% of the stream banks outside of Te Papakura o Taranaki are covered by riparian plans (October 2020).
