Flood study

LT Creek Flood Study


The LT Creek Flood Study has been prepared for Lake Macquarie City Council (Council) to define the existing flood behaviour in the LT Creek catchment and establish the basis for subsequent floodplain management activities. LT Creek is a tributary of Lake Macquarie draining a catchment area of some 7.5km2, extending north/north-west of the township of Fassifern. The catchment is drained by LT Creek and a number of unnamed tributaries, discharging to Fennel Bay, a semi-closed embayment of the broader Lake Macquarie waterway.

Catchment Description

Land use within the catchment primarily consists of bushland (60%), Newtsan Colliery (25%) and urban development (10%). The catchment is traversed by a number of transport corridors including the main-north railway, coal haulage routes associated with the Newstan operations and local roads. The urban communities of Fassifern and parts of Fennell Bay occupy the lower floodplain of LT Creek and represent the existing development subject to potential flood risk. This lower region of the floodplain is also largely affected by Lake Macquarie flooding.

Historical Flooding

There is an evident high flood risk exposure to the Fassifern community at the lower end of LT Creek. Major flood events resulting in substantial inundation to property have occurred in 1949, 1981, 1990 and most recently in June 2007.
