River Yeo, Lapford

The River Yeo is a tributary of the River Taw in Devon, England, sometimes known as the Lapford Yeo from the village of Lapford. It is one of several rivers of the same name in Devon, including another tributary of the Taw, the Barnstaple Yeo. The Lapford Yeo flows within 2 miles of the headwaters of another River Yeo, which is a tributary of the River Creedy.

The Lapford Yeo rises near South Tawton. It flows north through Bow and Zeal Monachorum to Lapford. It joins the Taw 1.5 miles below Lapford, just below Nymet Bridge. Its largest tributary is the River Dalch, which joins the Yeo near Lapford. The river's catchment area is almost twice the size of the Taw's catchment area above the confluence, but has significantly lower rainfall than the upper Taw valley.

The river was earlier called the Nymet, thought to be a Celtic word meaning 'shrine'. Several Nymet place-names remain in the area, including Nymet Tracey and Nymet Rowland, and it seems that the area may have been sacred in Celtic times.
