The proposal is to redevelop the existing Victoria Reservoir on Munday Brook, approximately 20 kilometres east of Perth. This is considered necessary by the Water Authority of Western Australia due to the age and condition of the existing dam, and timely in view of the current residential and rural development pressures being placed on the associated water catchments.

Redevelopment of the Victoria Reservoir would involve the creation of a new larger dam to replace the existing structure to gain additional water yield. Associated with this is the development of a pumpback water supply on the existing Bickley Brook Dam, using additional capacity available in the new Victoria Reservoir to store the winter flows from the lower Bickley catchment. The land included within the Victoria catchment area proposed to be flooded by the creation of the new dam is gazetted for water catchment.
