Steamers and other watercraft ran Anderson Lake from D'Arcy to the foot of the lake at Seton Portage (then known as Short Portage) a short 3 kilometre portage to Seton Lake, and from the foot of that lake another 5 kilometres to the trail's destination, the boomtown of Cayoosh Flat, which is today's town of Lillooet. The name D'Arcy was conferred on the settlement, which after the gold rush reverted to near-entirely First Nations population only, at the time of the construction of the Pacific Great Eastern Railway, when non-native settlers once again took up land in the area, including a general store and a set of cabins by the lakeshore.
Vessels and other watercraft traveled from D'Arcy to the shores of Anderson Lake, a brief 3-kilometer trek to Seton Lake, and then another 5 kilometers to Cayoosh Flat (now Lillooet), a rapidly growing settlement.
