The River Foss

The River Foss

The source of the River Foss is a spring situated adjacent to, and flowing into, Oulston Reservoir near Newburgh Prior, north of Easingwold. From there to the Blue Bridge in York, where it joins the River Ouse, the River Foss is 31km (19.5 miles) in length.

Using the River Foss

  • Only navigable for some 2km (1.5 miles) upstream of Castle Mills Lock
  • Headroom is restricted for Layerthorpe upstream by Peasholme Green and Foss Bank bridges with an air space of 2.4 metres
  • Foss Walk follows much of the river course from Blue Bridge to Oulston Reservoir and then on to Easingwold, a distance of 45 km (28 miles)
  • We are the 'navigation authority' for the River Foss. For required consents, queries or concerns about navigation contact our Asset and Property Management Team
  • Very limited opportunities for turning beyond Rowntree Wharf
  • There are no mooring points in the Foss Basin other than for vessels negotiating Castle Mills Lock
