South Thompson River

The South Thompson River is a significant tributary of the Fraser River in southern British Columbia, Canada. It originates from Shuswap Lake and flows northwestward to the city of Kamloops. There, it converges with the North Thompson River, and together they continue for approximately 100 miles before merging with the Fraser River at Lytton. The river was explored by Simon Fraser in 1808 and named in honor of David Thompson, an explorer and geographer. The Thompson River system is crucial for the Fraser River's flow, which is a major river in western North America.123
