Our rivers team manages, monitors and maintains 59 river and drainage schemes across Canterbury with the aim of protecting people and property from flooding and a total asset value of $691 million.

We build flood protection structures such as rock groynes, stopbanks, floodgates and anchored tree protection and our planting work protects wetlands which support riverbed bird nesting and enhances fisheries.

Our flood warning system draws on a sophisticated network of telemetered rain and river flow gauges, which allows us to provide you with vital up-to-date information. We also manage the rivers’ natural gravel resource as a source of aggregate for commercial or private use.
