The regions with the highest tidal movements (more difference between high and low tides) are tropical, and that is where the greatest growth rates of organisms also occur.
The world's largest tidal range of 16.3 metres (53.5 feet) occurs in Bay of Fundy, Canada, and the United Kingdom regularly experiences tidal ranges up to 15 metres between England and Wales in the Severn Estuary.
In France, it's at some places 12 meters (and more). RanceTidal Power Station, the first and oldest still working tidal power station of the world (opened in 1966) uses a tidal range of 10 m and more (today, e.g. the first low tides was 1.8 m, the following high tide 11.61 m).
Those mentioned medieval tidal mills are even to be found on rivers more inbound, today the still working Woodbridge Mill (Suffolk/England). But in nearby Ipswich had been some even earlier (in 1446, the two mills of Stoke Mill were a tidal mills, one for grain and one for fulling).
