    The River Douglas rises in the moors above Rivington Reservoir before flowing through Horwich, Wigan and out to the Ribble Estuary near Hesketh Bank. A valuable source of drinking water, the moors around Rivington Reservoir are also used for recreation. The operational catchment supports coarse fisheries and is used by canoeists. The River Douglas and its tributaries have three major water company sewage works; Wigan, Skelmersdale and Horwich. There are problems with weirs and culverts across the catchment which reduce wildlife movement. The catchment suffers from urban and diffuse pollution, industrial pollution and minewater discharges.
