The River Irwell is a river that runs for 39 miles through the counties of Lancashire and Greater Manchester in the north west of England. The river rises at Irwell Springs on Deerplay Moor one and a half miles north of the town of Bacup
in Lancashire. The river does not issue directly into the sea, instead feeding into the River Mersey
near Irlam. The river has been much modified over time and large sections of it were remodelled during the making of the Manchester Ship Canal
. The Irwell played a vital role in kickstarting the Industrial Revolution
and consequently became heavily polluted and completely devoid of fish but is now gradually being returned to health.
