Perennially popular with fishermen and home to several rare invertebrates , it has been polluted in its lower reaches in recent decades , due in part to the oil refinery at Stanlow and the arrival of the nearby M53 and M56 motorways , leading to schemes by environmental groups to clean up the area and to restock the fish population .
