The River Calder is a 13-mile (21 km) long river that is one of the main tributaries of the River Wyre in Lancashire, England.^[1] Like the other rivers in England with the name Calder, its name is thought to derive from a mixture of Old Welsh and Old British words meaning "hard and violent water or stream".^[2]
