Yakamia Creek is an urban drain running through residential and light industrial areas of Albany. The creek delivers high concentrations of nutrients to Oyster Harbour which threaten its health.

The City of Albany and the Regional Estuaries Initiative has transformed 1.1 hectares of Yakamia Creek in Centennial Park into a biofiltration wetland. Water is diverted from the creek and filtered through two basins, where native sedges and vegetation settle out sediments and remove nutrients before the water re-enters the creek.
