Course and features

Formed by the confluence of the North Para and South Para Rivers in the town of Gawler, the river flows generally west onto the Adelaide Plains. The mouth is in the Adelaide International Bird Sanctuary National Park—Winaityinaityi Pangkara, which consists primarily of mangroves in the tidal flats as the river empties into Gulf St Vincent. The outflow represents the boundary between the suburbs of Port Gawler on the northern bank and Buckland Park on the southern bank. The river descends 50 metres (160 ft) over its 41-kilometre (25 mi) course.[3]

Flooding

The Gawler is subject to periodic flood events and the cause of occasional flash flooding (during 1:10 to 1:50 year flood events). Major overtopping in large floods occurs along much of the river length. Significant flooding commences within Gawler township from both the North and South Para Rivers.[4]
