Reverse River? No, it's the Truro tidal bore that is drawing crowds

If you thought all rivers flow in one direction, then a visit to the Salmon River may have you scratching your head. In Truro, N.S., you can find a natural phenomenon that only occurs in a few places in the world. Despite its name, the Truro tidal bore is anything but boring.

The event occurs twice a day, attracting spectators who watch the river flow in the opposite direction. The surge of the incoming Fundy tide is so strong that it temporarily reverses the flow of several rivers that empty into the Bay of Fundy, including the Salmon River and Petitcodiac River in New Brunswick.

Tidal bores come in various shapes and forms, from a single breaking wavefront to a smooth wavefront followed by secondary waves. In areas where the river banks narrow, the compressing waters can reach a standing height of one metre, providing opportunities for river surfing.

The next time you are in Nova Scotia or New Brunswick check the tide charts to see the tidal bore up close. In the meantime, watch the video below to learn more.
