Petitcodiac River
The Petitcodiac River courses through Moncton, New Brunswick and Dieppe, New Brunswick, as well as and near the town of Truro, Nova Scotia, in Canada, into the Bay of Fundy. Because of its colour, it is often nicknamed the "chocolate river".
The Petitcodiac exhibits one of North America's only tidal bores, a regularly occurring wave that travels up the river on the leading edge of an incoming tide, and hence a tidal wave in the truest sense of the term. The bore is actually caused by tidal activity in the Bay of Fundy, which due to the rapid rise of water levels, forcibly sends a wave of water flowing upstream in rivers that normally flow into the ocean. This wave can vary in size depending on several factors including lunar activity, and travels up the river on top of the outgoing water flow.
There is a small, and understandably specialized industry which takes advantage of the tidal bore's regular presence in Truro, Nova Scotia by operating rafting expeditions when the bore is at its higher levels.
