Caboolture Catchment
The Caboolture Catchment covers approximately 468 square kilometres with its headwaters rising from Mount Mee. The main waterways are the Caboolture River and Waraba, Burpengary, Lagoon and King John creeks, together with numerous smaller waterways. The Caboolture River flows into northern Moreton Bay near Beachmere.
King John Creek
The King John Creek subcatchment starts near the town of D’Agular and runs parallel to the main catchment. The majority of the flow is along the is relatively flat and underlain by mostly sedimentary rock, with large areas of alluvium along the channels and extensive floodplains. There are small areas of impervious rocks in the upper parts and areas of unconsolidated sediments along lower King John Creek. In the lower parts, water can be held in the alluvium by the underlying sedimentary rocks until the tide goes out. Water movement is typically slow, with large tidal input and the potential for flooding.
Mangroves and saltmarshes (estuarine wetlands) remain along the lower reaches, together with lacustrine and palustrine wetlands.
