Thomson-Upper Yarra Aqueduct is of local significance for its role as a temporary part of the Melbourne water supply system and represents a direct response to the drought of 1967/8. (Supple 1991)

An open, unlined earthen channel (3 meters wide and 2 meters deep) diverts water from the Thomson River into the Upper Yarra catchment. Although the channel still carries some water, it does not appear to be maintained. Tree branches were observed to have fallen into the channel near the Thomson Valley Road and runoff from the road is draining into it. (Supple 1991)
