 Finnington Brook joins close to where the Roddlesworth itself falls into the River Darwen.Rising from the confluence of several small brooks, draining "Riley Green", "Marsh View" and "Brimmicroft", which meet close to Riley Green Bridge over the Leeds and Liverpool Canal, the brook runs eastward in a small, wooded valley below the canal.The river flows by the hamlet of "Finnington", picking up other streams heading north from "Stanworth", running by a hatchery and through a reservoir, joining the Roddlesworth on the south side of "Moulden Water Bridge".
