Flood protection in Southland
The Mataura, Ōreti, Aparima and Waiau systems drain large catchments into low-lying plains and estuaries. Heavy rain, saturated ground, local drainage constraints and, at times, snowmelt can combine.

Understanding flood risk in Southland
Invercargill, Gore, Winton, Riverton/Aparima, Te Anau and rural communities require plans matched to their river, drainage, estuary and access setting.
Mataura, Ōreti, Aparima and Waiau river systems
Confirm site-specific exposure through council mapping, local observations and qualified advice where required.
Low-lying plains, saturated ground and drainage
Confirm site-specific exposure through council mapping, local observations and qualified advice where required.
Estuaries, tide, snowmelt and prolonged river rises
Confirm site-specific exposure through council mapping, local observations and qualified advice where required.
River levels may continue to rise after rain eases locally. Watch upstream gauges and plan for water that cannot drain freely when rivers or tides are high.
Planning for people, places and continuity
Schools and early learning
Include rural roads, bridges, winter conditions and the time needed for families or buses. Store equipment above likely flood level and rehearse roles.
Iwi, marae and community facilities
Marae and community facilities should support whānau shelter and continuity, safe access and protection of wharenui, kitchens, water, power, records and taonga.
Councils, businesses and organisations
Farms, food processing, councils and public facilities should protect livestock access, refrigeration, pumps, chemicals, switchboards and essential operations.
Official Southland flood information
Use official warnings first, then regional monitoring and hazard information. Live readings can be provisional or interrupted during severe weather.
Prepare before water reaches the site
Use flood maps, LIM information, past events, drains, contours and site photos.
People first, then critical entrances, services, records, stock, plant and continuity functions.
Choose the forecast, gauge level or on-site observation that starts deployment.
Assign roles, label equipment, time the setup and review after every exercise or event.
Portable flood protection options
A doorway, garage, loading bay and whole-site perimeter do not need the same solution. Expected depth, flow, ground surface, width, corners, storage, deployment time and drainage behind the barrier all influence the choice.
A continuous barrier line can be configured around vulnerable areas.
Dry-weather training helps teams deploy safely and consistently.
Turn Southland flood information into a site plan
Send Special Solutions Flood Protection photos, measurements and what you know about how water reaches the property. We can help identify a practical starting point for a home, school, marae, council site or organisation.
