The River Cocker rises near to Yeat House Farm and Higher Knowe Hill[1] south of Quernmore, near Lancaster.

It runs south westerly through Cocker Clough Wood and Brunstow Wood, then by Hampson Green, before briefly turning north west when joined by Potters Brook at the hamlet of Potters Brook close to the M6 motorway , where it is channeled under the Lancaster Canal.

The river then skirts south around Cockerham, by Little Crimbles[2] before being swollen by Park Lane Brook and Lee Brook and flowing into saltflats below Cockersand Abbey on the Lune estuary.[3] The river is, approximately 17.5 km (10.9 miles) in length.[4]

Cockerham Marsh is a designated SSSI[5] and the Cocker Estuary is a favoured overwintering site of migratory pink-footed goose, which can be seen in flocks of over one thousand, at times. It is also nationally important for other winter seabirds, including oystercatcher, turnstone, grey plover, red knot (known simply as knot), curlew, common redshank and dunlin. In summer, it hosts impressive numbers of ringed plover.[6]

ETYMOLOGY

The name refers to cocker, a breeder of, hunter of, or fighter with game birds. This is appropriate given the local farming of poultry and the presence of many partridge and other game birds in the surrounding area.

WATER QUALITY AND POLLUTION.

The River Cocker, along with its neighbour the River Conder lie within the Pilling, Ridgy, Cocker and Conder Operational Catchment of the Environment Agency's Lune Management Catchment. The area is heavily pastorally farmed, with extensive cattle, sheep and poultry stock and agricultural pollution is identified as the main reason that waters have yet to attain “Good” status.[7]

United Utilities has made funding available for the “Cocker and Conder Clean Up”. Recent reporting has identified the overall quality of the water as “Moderate” for environmental pollution (ammonia and phosphates) and “Good” for chemical contamination.[8]
