INTRODUCTION

St Georges Basin is a coastal lagoon within the Shoalhaven City Council area (Figure 1). The Basin has a surface area of approximately 37 square kilometres discharging through the Sussex Inlet Channel to the Pacific Ocean at Bherwerre Beach. The total catchment area to the Pacific Ocean is approximately 327 square kilometres. The Basin itself therefore represents approximately 11% of the total catchment. This Floodplain Risk Management Plan covers the study area shown in Figure 1 including the Sussex Inlet Channel, the foreshore fringe area around St Georges Basin, and the lower reaches of the major tributary creeks (listed in Table 1). The study area is bound approximately by Sussex Inlet Road, the Princes Highway, The Wool Road, Jervis Bay Road and Naval College Road. A breakdown of the total catchment area is shown in Table 1.
