"Members of the Ottery fire crew positioned themselves in Klipfontein Road across from the Mary Harding School, while Epping's crew was at Koedoe and Hickory streets, and at Loerie and Cornflower street, and divers at the sewerage plant.
"Police divers were at Buckner Road in Hazendal. A buoy, thrown into the canal to ascertain a possible exit point, emerged at Koedoe and Hickory roads," the Fire and Rescue Service said in a statement.
It added, however, that the dive supervisor called off the search about three hours later because of the weather.
