Wagonga Inlet, Kianga and Dalmeny Flood Study

The Wagonga Inlet, Kianga and Dalmeny Flood Study was adopted by Council on 28 June 2016.

Study area

The Wagonga Inlet, Kianga and Dalmeny Flood Study (the study) includes four catchments: the Wagonga Inlet, Kianga Lake, the 'Duck Pond' and Mummaga Lake.

The Wagonga Inlet is a trained entrance estuary, with the township of Narooma located within the catchment.

The Kianga Lake, the Duck Pond and Mummaga Lake catchments are intermittently closed and open lakes and lagoons.

The township of Kianga is within the Kianga Lake catchment and the township of Dalmeny is within the Mummaga Lake and Duck Pond catchments.


The Wagonga Inlet, Kianga and Dalmeny Flood Study provides information on flood behaviour, including flood levels, potential hazards and impacts of projections for climate change on flood behaviour. The study also assists Council when undertaking flood-related planning decisions for existing and future developments.

The study is Stage 1 of the flood management process and does not recommend any management actions to manage the impacts on the community from flooding. A separate report will be prepared as Stage 2 of the flood management process, where detailed long-term management options can be investigated.

The primary objectives of the study are to:

  • determine the flood behaviour
  • determine provisional residential flood planning areas and flood planning levels
  • undertake provisional flood emergency response planning classification of communities
  • provide a model that can establish the effects of flood behaviour of future development
  • assess the sensitivity of flood behaviour to potential climate change effects such as increases in rainfall intensities and sea level rise.

The flood study report details the results and findings of the investigations made during the study.

Community engagement

A draft flood study was on public exhibition from 15 June to 24 July 2015 and community members were invited to read the draft and provide their feedback.

During the exhibition period, Council hosted a series of information sessions for community members and businesses to gain feedback on the draft study.

A questionnaire and information sheet was also distributed to residents and business owners within the study area.

The draft study and feedback provided by community members was presented to Council and considered prior to the plan's adoption on 28 June 2016.
