Stormwater flood studies have been carried out for the seven sub catchments within the Mid Georges River study area. The primary objective of each of the stormwater flood studies has been to define overland flood behaviour within the respective catchments through the establishment of appropriate numerical models. These models provide detailed information on the extent and depth of inundation for a range of design floods. The Mid Georges River study area is comprised of seven sub catchments, namely, Milperra, Kelso Swamp, East Hills, Lucas Road, Picnic Point, Morris Gully and Little Salt Pan Creek. The sub-catchments are based on natural topographical divides and are bounded by the Georges River along the east and south of the study area. Encompassing a total area of approximately 30 square kilometres, the study area represents a significant proportion of the Local Government Area.
