River Ryburn

The River Ryburn is a river in West Yorkshire, England. It flows through the villages of Rishworth, Ripponden and Triangle before flowing into the River Calder at Sowerby Bridge.

The river becomes known as Ryburn at the confluence of a small unnamed stream and Black Castle Clough to the east of Blackstone Edge Reservoir. It flows east parallel to the A58 Rochdale Road into Baitings reservoir. It emerges from the east end of the reservoir for a short time before flowing into Ryburn Reservoir. The river flows out of the east end of the reservoir just to the north of the village of Rishworth, before turning north east and flowing through Ripponden. After leaving the town, it flows north to Triangle before turning north east again, flowing through Sowerby Bridge and joining the River Calder.
