Ouse River

The River Ouse is a river in North Yorkshire, England, formed by the confluence of the River Ure and Ouse Gill Beck. It flows through the city of York and the towns of Selby and Goole before joining the River Trent at Trent Falls to form the Humber Estuary. The river is approximately 52 miles long and has a wide, flat plain that can be prone to severe flooding. The Ouse's system of tributaries drains a large upland area of northern England, including the Yorkshire Dales and North York Moors. The river has been used for commercial navigation since the time of the Romans and is tidal up to Naburn Locks. There are several riverside SSSIs associated with the Ouse, including Clifton Ings and Rawcliffe Meadows, Fulford Ings, Naburn Marsh, and Acaster South Ings
