Otago’s Water Plan is being reviewed by ORC. We are taking a staged approach to the review based on 'mountains-to-sea' catchment areas called Freshwater Management Units (FMUs). In Otago we have set five FMUs: Clutha/Mata-Au, Taieri, North Otago, Dunedin Coastal and Catlins.




Our southern-most rohe, the Catlins Rohe, has scenic coastal landscapes and dense temperate rainforest, making it a popular tourist destination. It has a population of approximately 1,200 people, many of who live in the main settlement of Owaka.   

As we go through this new FMU process, there may be some rules set for the Catlins Rohe that differ from other areas. This will be done in consultation with the local community to ensure that waterway management reflects local values and objectives.

Information and resources

We carry out monthly water quality testing as part of our State of the Environment (SOE) testing. Please note that SOE reports are based on five years of data.

Read more about water quality in this area at the Land, Air, Water Aotearoa website, including the "Can I swim here?" section which is updated weekly in summer months.
