The Bay of Fundy is an arm of the Gulf of Maine. It has the highest tidal range.
Tides are semidiurnal, with two highs and two lows each day. About 6 hours and 13 minutes separate them.
In one half-day cycle, about 100 billion tonnes of water flow in and out. That is a lot of bathwater.
More water moves here than all rivers combined.
This power comes from tidal resonance in a funnel-shaped basin. Most rivers draining into it experience a tidal bore.
Before a causeway in 1968, the Petitcodiac River had a tidal bore up to 2 metres high.
The highest water level ever recorded reached 21.6 metres in October 1869. A tropical cyclone coincided with a spring tide.
The Annapolis Royal Generating Station was a 20 MW tidal power station. It shut down in 2019.
