The Petitcodiac River exhibits one of North America's few tidal bores: a regularly occurring wave that travels up the river on the leading edge of the incoming tide.
The bore is as a result of the extreme tides of the Bay of Fundy.
Originally, the bore was very impressive, sometimes between 1 and 2 metres (3 ft 3 in and 6 ft 7 in) in height and extending across the 1 kilometre (0.62 mi) width of the Petitcodiac River in the Moncton area.
This wave would occur twice a day at high tide, travelling at an average speed of 13 km/h (8.1 mph) and producing an audible roar.
Unsurprisingly, the "bore" became a very popular early tourist attraction for the city, but when the Petitcodiac causeway was built in the 1960s, the river channel quickly silted in and reduced the bore so that it rarely exceeds 15 to 20 centimetres (5.9 to 7.9 in) in height.
On April 14, 2010, the causeway gates were opened in an effort to restore the silt-laden river.
A recent tidal bore since the opening of the causeway gates measured a 2-foot-high (0.61 m) wave, unseen for many years.
