Floodplain Management

Glenelg Hopkins CMA minimises potential flood damage by managing flood risk and protecting floodplains from inappropriate development.


Floodplains provide significant economic and environmental benefits. They support flora and fauna habitats, protect streams from high sediment and nutrient loads and maintain water quality. Floodplains convey moving floodwaters and provide temporary storage for that water.

Statutory responsibilities of Glenelg Hopkins CMA under the Water Act (1989) are to:

  • Find out how high floodwaters are likely to rise.
  • Provide advice to Council on the suitability of a proposed development. Advice may be in the form of an approval, with or without conditions, or an objection.

Regional Floodplain Management Strategy vision

With the involvement of the affected local community to maintain and enhance the capacity of the floodplain to convey and store floodwater while implementing flood management measures which both reduce flood risk and damage cost, yet still reap the hydraulic and environmental benefits of the floodplain.

How you can help

Photographs and recollections of previous floods are tremendously useful in helping the flood management team to understand the complexity of different river systems and floodplains.

If you have any photographs of flooding in our region and would like to add them to the flood management team's archive, please click here.

If you don't have your photographs electronically, call in at any Glenelg Hopkins CMA office where the photograph will be scanned and handed straight back to you.
