It is formed at Swindale Head where Mosedale Beck, from the slopes of Tarn Crag, joins Hobgrumble Beck from Selside Pike.
The stream flows north-east along Swindale and joins the River Lowther near Rosgill between Shap and Bampton.
Its waters then flow via the River Eamont into the Solway Firth.
[1][2] In 2016, 750 metres (2,460 ft) of straightened channel was replaced with 890 m (2,920 ft) of a new sinuous channel, reconnecting the stream to its surrounding floodplain.
