The Patawalonga Lake System is designed to divert urban stormwater to the sea via the Barcoo Outlet and use Gulf St Vincent tides to flush the lake with seawater. It is a man-made lake 1.6 km long running parrallel to the coastline from Glenelg to West Beach.
The primary purpose of the Patawalonga Lake System is to:
- stop Gulf St Vincent tides from flooding Glenelg North and Adelaide Airport.
- divert stormwater in the Sturt river, Keswick and Brownhill Creeks from flooding property along the lake.
- provide a safe and healthy marine facility in the Glenelg precinct for water sports and aquatic life.
