[1] Bishop River Provincial Park surrounds the upper course of the river, from the source at the Lillooet Icecap to midway along its course above its confluence with the Southgate.
[2][3] The Bishop River was named for Richard Preston Bishop, born September 18, 1884, in Starcross, Devon, who was a British Columbia Land Surveyor.
He had been an officer in the Royal Navy in 1906-07 and served as a captain in World War I, but returned to British Columbia to resume work as a surveyor.
Many mountains in the Pacific Ranges, including Mount Sir Francis Drake and Mount Queen Bess, and the Golden Hinde on Vancouver Island, were named in the 1930s as proposed by him.
Of the many Elizabethan-era names in the Coast Mountains, many are in the area of the Bishop River, including Mount Raleigh which stands on the southeast side of the Bishop-Southgate confluence.
