Historical Uses of the Thompson River (British Columbia)

The Thompson River—major tributary of the Fraser River in British Columbia—has served as a vital corridor and resource for millennia:

1. Indigenous Transportation & Trade (Pre-contact – Present)

• Secwépemc (Shuswap), Nlaka'pamux (Thompson), Syilx (Okanagan) nations used canoes (cottonwood, birchbark) for travel, trade, hunting, fishing.
• Major trade route: Interior Plateau ↔ Coast (via Fraser). Goods: obsidian, dentalia, furs, dried salmon, pemmican, copper.
• Cultural sites: Kekuli (pit houses), fishing stations (dip-netting), rock art along river.

2. Fur Trade & European Exploration (Early 1800s – 1860s)

• North West Company / Hudson's Bay Company: Established posts (Kamloops = Fort Kamloops, 1812).
• David Thompson (explorer): Mapped river 1811; namesake.
• Brigade trails: Horses carried furs from interior to coast (Fort Langley, Fort Vancouver).
• Gold Rush (1858–1860s): Fraser & Thompson gold → 30,000+ miners. River = supply route. Yale, Lytton, Barkerville boomtowns.

3. Fishing: Sustenance & Economy

• Salmon (Sockeye, Chinook, Coho, Pink, Chum) + Steelhead — cultural keystone for Secwépemc/Nlaka'pamux.
• Traditional dip-netting at rapids (e.g., Black Canyon) — continues today.
• Commercial fishery (late 1800s–present) — now heavily managed/conservation-limited.

4. Mining: Gold, Copper, Coal

• Placer gold: Thompson, Fraser, tributaries (Tranquille, Deadman, Bonaparte).
• Porphyry copper: Highland Valley Copper (Logan Lake) — one of world's largest.
• Coal: Merritt, Hat Creek basins.
• Acid rock drainage legacy — ongoing remediation.

5. Hydroelectric Power (1950s – Present)

• BC Hydro dams: Mica, Revelstoke (on Columbia, but Thompson watershed contributes), plus Thompson tributary diversions.
• Regulates flow: reduces spring flood, increases winter flow. Impacts salmon, riparian ecology, sediment.

6. Recreation & Tourism (Modern)

• Whitewater rafting/kayaking (Thompson Canyon, Fraser confluence).
• Fly fishing (steelhead, trout).
• Hiking, camping, wildlife viewing (bighorn sheep, bears, eagles).
• Cultural tourism: Secwépemc Museum, Kekuli sites, gold rush heritage.

The Thompson remains a working river—balancing hydropower, fisheries, Indigenous rights, agriculture, and recreation in a warming, drying climate.
