After an early lunch we drove down to Glenelg for a walk around the marinas and the shopping strip. We parked near the replica of HMS Buffalo that is moored on Lake Patalonga. HMS Buffalo is an exact replica of the vessel that brought free settlers to Adelaide in 1836. It is moored in Patawolonga Lake and is used as a floating restaurant. Patawalonga Lake is a man-made lake approximately 1.6 kms long that has barage gates at each end to let water in at high tide at Glenelg, and let water out at the northern end of the lake at low tide. While the flow of water keeps the water from getting stagnanat it was not clear to us how the boats get in and out.
