The Roselea Boulevard Compensation Basin (RBCB) was developed together with surrounding public open space within the Roselea Residential Estate, situated in the City of Stirling, Western Australia. The RBCB is susceptible to algal blooms (Potamogeton cripsus), particularly in the summer months, resulting in amenity and odour complaints from residents. Water Corporation commissioned The University of Western Australia undertake an assessment of the sources of water and nutrients to RBCB, and to make recommendations on actions that might ameliorate eutrophication of the basin.
