Elliot Lake - Little Lake Floodplain Risk Management Plan

Brief description

__Executive Summary__

Cardno were commissioned by Shellharbour City Council to undertake the Floodplain Risk Management Study and Plan
for the Elliot Lake – Little Lake catchment area

Background

The Elliot Lake – Little Lake catchment lies south of Lake Illawarra and drains to the Tasman Sea via Elliot Lake – Little
Lake. The catchment covers approximately 12.4 km2 and includes the suburbs of Barrack Heights, Shellharbour,
Flinders, Blackbutt and large parts of Mt Warrigal and Warilla. The majority of the catchment is urbanised with
predominantly residential development and some business and light industry. Blackbutt Forest Reserve and the area
upstream of the Princes Highway in the southern part of the catchment form the two main undeveloped areas.
The main waterways of the catchment are Bensons Creek, Bensons Tributary and Tongarra Creek. Bensons Creek and
Bensons Tributary drain the northern part of the study area, whilst Tongarra Creek drains the southern part. Both creeks
drain into Elliot Lake – Little Lake which discharges to the Tasman Sea at Barrack Point.
