Amportane Bridge Over The Knockoneil

The Knockoneil River (sometimes spelled Knockoneill), is a small to medium sized river in Northern Ireland located near Maghera. It starts on Carntogher Mountain then flows eastwards towards Swatragh. Knockoneil is a townland in the rural area of Slaughtneil and is the townland the rivers named after. The Knockoneil starts its course and its a similar width to the Grillagh River. The river widens as it passes through Swatragh and onwards to Upperlands where a lot of hydro energy from the river is used for Clarke's mill onwards through Upperlands.The river flows quite swiftly through the village of Upperlands passing under Upperlands and Boyne Bridges as well as the Old Mills. From Upperlands it quiets down through the Countryside outside Upperlands and on to Culnady where it flows under Dunglady Bridge an old bridge near Culnady named after Dunglady Fort which its name means Fort Above The Clady. Shortly downstream it merges outside Culnady with the Grillagh River to form whats known as the Clady River.

Knockoneil River Means Nialls Hill River.
