About the River Great Ouse
The River Great Ouse is a river in England, the fifth longest in the United Kingdom, and longest of several British rivers called "Ouse". It flows mostly north and east, from Syresham in Northamptonshire, through Buckinghamshire, Bedfordshire, Cambridgeshire and Norfolk, before draining into the Wash and the North Sea near Kings Lynn. Authorities disagree both on the river's source and its length, with one quoting 160 mi (260 km) and another 143 mi (230 km). The Great Ouse has been historically important for commercial navigation, and for draining the low-lying region through which it flows; its best-known tributary is the Cam, which runs through Cambridge. Its lower course passes through drained wetlands and fens and has been extensively modified, or channelised, to relieve flooding, stabilise its path, and provide a better route for barge traffic.
