In Saint John the height difference from low to high tide is approximately 8 metres (28 ft) due to the funnelling effect of the Bay of Fundy as it narrows. The Reversing Falls in Saint John, actually an area of strong rapids, provides one example of the power of these tides; at every high tide, ocean water is pushed through a narrow gorge in the middle of the city and forces the Saint John River to reverse its flow for several hours.
