Inflow to the lake is from small tributaries that discharge initially into winter-wet flats.
Lake Yealering inflow is received from Wogolin and Boyning Gully located to the south east and both enter via the swamp.
Stream flow from the lake discharges to Cuneenying Brook and then to the Avon River.
[3] Surrounding the lake are four types of vegetation: low samphire shrubland containing Tecticornia indica and Tecticornia pergranulata, low open woodlands of Banksia prionotes with an understorey of Ehrharta calycina low shrubland and grassland, Casuarina obesa woodlands over Tecticornia indica and T. pergranulata samphire shrubland, and low open woodlands with an overstorey of Eucalyptus sargentii with an understorey dominated by Melaleuca atroviridis shrubland.
[4] The traditional owners of the area are the Njakinjaki group of the Noongar peoples,[6] who have inhabited the region for tens of thousands of years.
