Glenelg Shire Council, in partnership with the Glenelg Hopkins Catchment Management Authority, has conducted a study to better understand flooding near the lower Glenelg River and estuary.
The study, funded by the Australian Government and Council, commenced in 2022. It aims to provide accurate flood information to help with future planning and reduce flood risks, particularly in the towns of Dartmoor and Nelson.
Flood risks are well-known for the upper and middle parts of the Glenelg River, but less is known for Dartmoor and Nelson. Since records began, significant floods in the area have occurred in 1946, 1955, 1960, 1983, and 2016.
The study findings indicate the frequency of flood events like these are predicted to increase and be more severe by the year 2100 due to increased rainfall and sea level rise.
As a result of the study, new flood risk maps will be proposed in an upcoming planning scheme amendment to ensure any new development within the modelled flood area considers flood risk. This means any new structures in the identified overlay areas will need to be assessed through a planning application.
