River Ouse

The River Ouse is a river in North Yorkshire, England. Hydrologically, the river is a continuation of the River Ure, and the combined length of the River Ure and River Ouse makes it, at 129 miles , the sixth longest river of the United Kingdom and the longest to flow entirely in one county. The length of the Ouse alone is about 52 miles but the total length of the river is disputed.

It is a matter of opinion as to whether the River Ouse is formed at the confluence of the River Ure and the much smaller Ouse Gill Beck at Cuddy Shaw Reach near Linton-on-Ouse, about six miles downstream of the confluence of the River Swale with the River Ure. An alternative opinion is recorded in a publication published in The Yorkshire Post in a series dated 1891, written and illustrated by Tom Bradley. His description and bird’s eye view maps - specifically in his account of the River Swale - suggests that the River Ouse starts at the confluence of the Swale and the Ure. His narrative states that the Ouse has no specific source, simply flowing from the stated confluence until it runs into the Humber at the confluence of the Ouse and Trent.
