The River Petteril is a river in Cumbria, which is a tributary of the River Eden. The river arises near the village of Penruddock and flows roughly north-easterly to Greystoke, where it is joined by the River North Petteril. Other tributaries of the Petteril include Stony Beck, Calthwaite Beck, Blackrack Beck, and Woodside Beck. The Petteril is crossed by the M6 mototway and eventually joins the Eden at Carlisle.
The River Petteril is a river running through the English county of Cumbria.
The source of the Petteril is near Penruddock and Motherby, from where the young river runs southeast through Greystoke, Blencow and Newton Reigny, before passing under the M6 motorway, after which the river turns north, and the motorway roughly follows the course of the river towards Carlisle.
Having reached Carlisle, the Petteril runs a course through the south east of Carlisle, dividing the suburbs of Harraby, Upperby and Botcherby before joining the River Eden on its journey to the Solway Firth.
