While the actual naming is unknown, it is likely that the waterway was named after John Flinders Scott who owned a considerable portion of the Port Hills along with a sheep station at Parnassus, a large orchard at Chaneys, an apiary at Broadfield and a 25 acre holding at Opawa that included his house Hawford on what is now Hawford Road. Scott was also a Heathcote County councillor 1926 – 1941. It is entirely possible that Scott himself contracted for the drain to be dug on his property to improve it.
An alternative would be that it is named after George Scott, a prominent Christchurch businessman who was chairman of the Heathcote Road Board 1905 – 1911 and chairman of the Heathcote County Council 1911 – 1916.
