Loch McNess
Loch McNess is extremely significant to the Aboriginal people of the area. According to Aboriginal tradition, the lake is inhabited by a Waugal (rainbow serpent) and the activities of the Waugal ensure that the springs that feed the lake continue to flow.
The Lake was originally known as Yanchep Lake. Aboriginal people dug the starchy tubers of the yangeti (bulrush) from Yanchep Lake, hence the name, which means 'place of the bulrush'. Yangeti was a very important food for indigenous Australians. Historic records also record the name Mambibby for the area ('mam' means 'father', and 'bibby' means 'breast milk' or 'mother').
It was renamed after philanthropist Sir Charles McNess donated £11,600 to the State in the 1930s to alleviate distress among the large numbers of unemployed. The donation was used by the State Gardens Board to employ sustenance workers on major developments within the park. They extended the sealed road from Wanneroo, connected a single wire telephone, reclaimed and ramped the foreshore of the lake, supplied the park with power and water, built internal roads and paths, fitted Crystal Cave with electric lights and established a children's playground near Caves House.
The two kilometre Wetlands Trail starts at this point and circumnavigates Loch McNess. It takes about 30-40 minutes to complete. Yanjidi is a variation of the word yanget, the Nyoongar Aboriginal word for the native bulrush that is a prominent feature of the walk.
