Canals & Locks

A system of canals, The Islands Estate's key feature

A key feature of The Islands Estate is a system of canals meandering between exquisitely designed waterfront homes. The six kilometres of navigable water at various points in the estate also feature several islands and jetties to accommodate boats. The water in the canals functions independently of the adjacent Hartbeespoort Dam as the canals have been constructed above the Dam's water level.

The water in the canal is continuously circulated through an artificial wetland system consisting of a series of interconnecting dams covered with water-loving plants and reeds to ensure water quality of a high standard.

Access from the canals to the Hartbeespoort Dam is made possible by means of bi-directional water locks, with a similar system connecting the lower and upper canals. The bi-directional water lock allows for lowering or rising of six boats at a time (three up and three down) at the two water locks. The transfer time of boats in the water lock is kept to less than ten minutes. Freeboard between the canal water level and lower arch of the bridges is three metres or more, thus catering for most sized power boats used on the Hartbeespoort Dam.

The Extra Mile Canal event has been included in the South African swimming calendar and forms part of the elite swimming events held annually by Swimming South Africa.
