The Clutha Delta — extending from north of Balclutha to the sea — faces a variety of natural hazards, many of which are expected to worsen with ongoing changes in the landscape and climate.
The Clutha Delta - a low-lying area of land of around 130 square kilometres - is exposed to a variety of natural hazards including flooding, high groundwater and drainage issues, coastal erosion and inundation, and earthquake related hazards. As these hazards change over time, the responses we rely on today to manage them may need to change to ensure resilience in the future.
Recognising this, the Otago Regional Council is working with the Clutha District Council and Emergency Management Otago and is planning to work closely with mana whenua to develop the Clutha Delta Natural Hazards Adaptation Programme.
Community involvement in the programme is important as we develop a better understanding of natural hazards in the area and how they may impact communities now and in the future.
The programme will engage with the communities in the delta so that options for future responses are informed by local knowledge and values and support long-term wellbeing and resilience.
Otago Regional Council works to investigate natural hazard risks in the area, and to reduce risk from flooding through ongoing management and maintenance of the Lower Clutha Flood Protection and Drainage Scheme which provides flood protection and land drainage. This scheme reduces flood risk to Balclutha, Kaitangata and Stirling, and supports agriculture across the delta.
