Yangebup Lake continues to be of mythological, historical and ceremonial importance to the local indigenous people and is a registered site of Aboriginal cultural significance.

Large scale farming was gradually abandoned in favour of market gardens because of the poor soil in the area, which required fertilising to be productive.

The Jandakot Wool Scouring Co., as the enterprise was known, operated for 70 years at the location, resulting in ongoing pollution issues from its discharge, with lead, chromium and arsenic having been found in the lake sediment.

[2] The lake continues to suffer from inflows of nitrogen and phosphorus through fertiliser runoff from surrounding agriculture and suburban gardens, causing it to be hyper-eutrophic.

This causes algae blooms in the lake and, as a knock-on effect, allows large numbers of midges to breed, with attempts made to stop this cycle.
