Conjola Lake is located on the New South Wales South Coast, about 200km south of Sydney and 50km south of Nowra. The lake is within the local government area of the City of Shoalhaven. Planning landuse of adjoining lands come under the statutory responsibility of Shoalhaven City Council. Conjola Lake is an estuarine lake that is connected to the Tasman Sea via a shoaled entrance channel. The lake has a surface area of 4.3 square kilometres which can be conveniently divided into three sections; the entrance channel, main body and secondary lake (Berringer Lake).

The primary objective of the Lake Conjola Flood Study is to examine and define the flood behaviour of Conjola Lake in the vicinity of the villages lying on its foreshores, which include Lake Conjola village, Conjola Park, Fisherman’s Paradise, and Berringer Lake. It is proposed that the Flood Study will provide input for the subsequent floodplain management study and plan. Specifically, this study developed computer models to predict the flood risks for areas surrounding Conjola Lake. These models have been used to determine hydraulic categories and the provisional flood hazard.
