The City of Cape Town proposes the redevelopment and upgrade of the weirs at Zeekoevlei and Rondevlei that are located within the False Bay Nature Reserve.
The proposed redevelopment of the ‘weir complex’ is to supplement other medium-term interventions, including the dredging of Zeekoevlei , to improve the overall water quality of this Ramsar site.
Both Zeekoevlei and Rondevlei are managed by a system of penstock sluice gates to allow for the water level to be dropped to a minimum depth, which is known as the annual ‘drawdown’, usually at the end of the summer sailing season.
The intention of the drawdown is to remove nutrient-rich water and sediment from the system, and to increase the capacity of the vleis prior to the winter rainfall season to reduce the risk of flooding of surrounding areas.
