 Most, however, came via a water route from the foot of Kamloops Lake, just east of Cache Creek and so near the main trails associated with the Fraser rush and the new goldfields being found north in the Cariboo.From there, steamer services travelled from Kamloops Lake via Fort Kamloops and up the South Thompson to reach Little Shuswap Lake and via the Little River to Shuswap Lake (also called, especially in the old days, Big Shuswap Lake).Shuswap Lake is one of the largest lakes in southern British Columbia, effectively an H-shaped series of four freshwater inlets, the northeast arm leading to the mouth of the short but powerful Seymour River.
