Tengawai River
The Tengawai River or Te-Ana-a-wai River is a hill-fed river and a tributary of the Opihi River in New Zealand's South Island.[1]
Geography
The Tengawai River flows east for 35 kilometres (22 mi) before joining the Ōpihi River at Pleasant Point, 20 kilometres (12 mi) north west of Timaru. It is bounded by land developed for agricultural.[2]
Ecology
The Tengawai River is open to fishing each year from 1 October to 30 April. Only brown trout and salmon are allowed to be fished.[3]
The riverbed provides habitat for threatened river bird species, such as pīwakawaka, silvereye, and grey warbler. The vegetation buffers the river from adjoining land use activities and provides habitat to the threatened New Zealand long-tailed bat and may facilitate the dispersal and persistence of other indigenous fauna including lizards and forest birds.[2]
History
In March 1986, after strong rainfall, the Tengawai River bursted its banks and flooded Pleasant Point, where 1,160 people were evacuated. This was the worst flood in the history of South Canterbury.[4][5]
