Ouse is the name of four major rivers in England. The Great Ouse rises in Northamptonshire and flows for about 160 miles (260 kilometers) through the counties of Buckinghamshire, Cambridgeshire, and Norfolk and also the Central Bedfordshire Unitary Authority, until it reaches the Wash. It flows past the towns of Bedford, Huntingdon, Ely, and King’s Lynn. The Little Ouse, about 25 miles (40 kilometers) long, meanders mostly along the boundary between the counties of Norfolk and Suffolk and flows into the Great Ouse.
The main part of the Yorkshire Ouse is 45 miles (72 kilometers) long and is formed by the convergence of two rivers, the Ure and Swale, that flow from the Pennines. The Yorkshire Ouse then joins the River Trent to form the Humber estuary. The Sussex Ouse, about 30 miles (50 kilometers) long, flows into the English Channel at Newhaven.
