The primary objective of this flood study is to define the flood behaviour under historical, existing and future conditions (incorporating potential impacts of climate change) in the Lake Illawarra, Mt Warrigal and Oak Flats Catchment for a full range of design flood events.

Lake Illawarra is a shallow coastal lagoon located between the ocean and the cliffs of the Illawarra escarpment. The elevated areas of the catchment area closer to the escarpment are mostly forest and rural areas. The lower areas closer to the lake are flatter and include a mix of residential, commercial and heavy industrial development.

The area experiences flooding from floodwaters rising from Lake Illawarra as well as localised heavy downpours causing hazardous stormwater overland flows. This area also includes the Shellharbour City Centre Wet Basin, a prescribed dam as defined by the NSW Dam Safety Committee with a significant flood consequence category.
