River Yeo, Lapford
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.
