The Severn River, mostly just known as " The Severn "is the longest river in Great Britain at about 220miles (354km)
Its source is in the Cambrian Mountains of Mid Wales, flowing through Shropshire, Worcestershire and Gloucestershire, to end in the Severn Esutury where it discharges into the Bristol Channel.
The Navigation commences at Pool Quay, near Stourport and continues down to Gloucester Docks.
The river becomes tidal at Maisemore, 2.5miles northwest of Gloucester, although it is only normally at the Equinoxal Spring Tides that the tide will be higher than the Gloucester wier.
There are a number of bridges crossing the Severn, the most famous of which is The Iron Bridge built by Abraham Darby III and was opened on 1st January 1781.
The most famous feature of the Severn, is the Severn Bore. This happens when the incoming tide moves up river as an advancing wave. At the Spring and Autumnal Equinox this becomes a most spectacual sight which many go to see and experianced surfboarders and some canoeists aim to ride.
But, equally the Bore and the strong tide makes it difficult to time any canoeing below Gloucester, plus the very wide estury with dangerous mud banks means that our journey from Gloucester is via the Gloucester Sharpeness Canal.
