River Ure

The River Ure in North Yorkshire, England, is about 74 miles (119 km) long from its source to the point where it becomes the River Ouse. It is the principal river of Wensleydale, which is the only major dale now named after a village rather than its river. The old name for the valley was Yoredale after the river that runs through it.

The Ure is one of many rivers and waterways that drain the Dales into the River Ouse. Tributaries of the Ure include the River Swale and the River Skell.

The earliest recorded name of the river is Earp in about 1025, probably an error for Ear ƿ, where ƿ represents the Old English letter wynn or 'w', standing for ƿæter ("water"). By 1140 it is recorded as Jor, hence Jervaulx (Jorvale) Abbey, and a little later as Yore. In Tudor times, antiquarians John Leland and William Camden used the modern form of the name.

The name probably means "the strong or swift river". This is on the assumption that the Brittonic name of the river was Isurā, because the Roman name for Aldborough was Isurium; intervocalic s is known to have been lost in Brittonic at an early date. This explanation connects the river name with an Indo-European root is- meaning "strong" and the names of the Isar in Germany and the Isère in France.

The source of the river is Ure Head on Abbotside Common, where it flows west-southwest to the valley floor and then turns south. Where it reaches the A684, it turns east along Wensleydale as far as Wensley. From here, it flows south-east to Jervaulx Abbey and shortly after south to Mickley. Here, it returns east and then south to Ripon. A little way after Ripon, it flows east again to Boroughbridge.

To the east of Boroughbridge, the Ure is joined by the River Swale. About 6 miles (9.7 km) downstream of this confluence, at Cuddy Shaw Reach near Linton-on-Ouse, the river name changes to the River Ouse.

Upper Wensleydale is a high, open, and remote, U-shaped valley overlying Yoredale Beds. The gradient is gentle to the north end of the valley, becoming steeper further south. Glacial drumlins lie either side of the river, which is shallow but fast flowing. The river is fed from many gills cutting through woodland and predominantly sheep farmsteads. The Settle to Carlisle railway runs along the western side of the valley here.

Mid Wensleydale is made of Great Scar limestone under Yoredale beds that make up the valley sides, which are marked with stepped limestone scars. The valley floor is made from glacial drift tails and moraine. The river here is broad and gently flowing in meanders in a stony channel. The four tributary valleys contribute to several waterfalls in this area.
