Waihopai River
The Waihopai River is a significantly modified river catchment in the east of the Southland Plains. Its headwaters are on the Edendale terrace, adjacent to the lower Mataura Valley, and it flows through Southland’s largest city, Invercargill.
Much of the lower Waihopai River has been straightened with flood banks along its margins to the outfall at New River estuary. The land in the catchment has largely been drained and cleared over the years to allow for the development of intensive agriculture. The lower river also is influenced by Invercargill’s stormwater network and the tidal fluctuation of the New River Estuary.
