Flooding is a relatively frequent occurrence in the Upper Nepean valley. Periodically, water from the Nepean River flows across the floodplains and into low lying areas of the Camden township, parts of South Camden and Elderslie and the extensive floodplains associated with the Narellan and Matahil Creeks. Flooding from these particular tributary streams, as well as Navigation, Sickles, Cobbitty and Bringelly Creeks can also cause flooding in the Camden Local Government Area. The primary objectives for the Camden Floodplain Management Plan are:

• to reduce the social and economic impact of flooding on individual owners and occupiers of flood prone property;
• to reduce private and public losses resulting from floods;
• to minimise adverse economic impacts on the commercial centre of Camden and to foster flood compatible development;
• alert the community to the extent of flood prone land and the associated hazards in the Camden LOA; and
• inform the community and seek their support of Council's policies in relation to the use and development of flood liable land in the Camden LOA.
