where does the river mersey start
The river may have been the border between the ancient kingdoms of Mercia and Northumbria and for centuries it formed part of the boundary between the historic counties of Lancashire and Cheshire. The start of the Mersey is at the confluence of the River Tame and River Goyt in Stockport.It flows westwards through the suburban areas of south Manchester towards Warrington where the river widens before it then narrows as it passes between the towns of Runcorn and Widnes.he river empties into Liverpool Bay on the Irish Sea, after a total course of 68 miles (109 km). From 4 metres (13.1 ft) neap tide to 10 metres (32.8 ft) spring tide, the River Mersey has the second highest tidal range in Britain â second only to the River Severn.
