River Medlock

From Wikipedia, the free encyclopedia

The River Medlock is a river of Greater Manchester in north west England that flows for 10 miles before joining the River Irwell in central Manchester.

Rising in the hills that surround Strine Dale just to the east of Oldham it flows through the steep-sided wooded gorge that separates Oldham from Ashton-under-Lyne and Daisy Nook Country Park with its 19th century aqueduct carrying the disused Hollinwood Branch Canal over the shallow river. Along its course, the valley provides a welcome respite from the urban sprawl of the east Manchester suburbs, and is perennially popular with locals.

The final miles of the river's flow to the River Irwell have been extensively modified. The river is culverted beneath the former UMIST campus (London Road to Upper Brook Street), and again at Hulme Street, appearing briefly at Gloucester Street before flowing under the former gasworks at Gaythorn, reappearing at City Road East. At Deansgate the river meets the Bridgewater Canal head on. Normally the level of the river is several feet below the level of the canal. The river is carried in a tunnel under the Castlefield canal basin, reappearing at Potato Wharf, where it is supplemented by excess canal water draining into a circular weir. When the river is in spate the tunnel cannot cope and river water enters the canal, flows across the basin, and exits via the weir and manually operated gates. A quarter of a mile further on and 50 yards from the junction with the Irwell, the currently disused Hulme locks lead up to the canal.

In the latter part of the 18th century the river was navigable at least between the Bridgewater Canal (at Deansgate) and India House (on Whitworth Street). At India House was the entrance to a tunnel used to carry coal to a wharf at Store Street (by Piccadilly station)^[1]. The tunnel mouth is still visible. The tunnel was rendered obsolete by silting of the river and the construction of the Rochdale Canal.

The area just south of Oxford Road station enclosed by the railway line and the loop in the river was known as Little Ireland, and was discussed by Friedrich Engels^[2].
