The Thompson River is a major tributary of the Fraser River, flowing 489 km through British Columbia, Canada. The river has a rich history, beginning with the Indigenous peoples who have lived along its banks for thousands of years. It was also an important transportation route during the fur trade era and later for the Canadian Pacific Railway. The river's hydrology is affected by seasonal snowmelt and precipitation, resulting in high water levels in the spring and low water levels in the summer. The river is home to several reservoirs and dams, including the Nicola Dam and Reservoir and the Mica Dam and Reservoir. These reservoirs serve as important sources of hydroelectric power for the region. The Thompson River is also an important source of irrigation water for agricultural lands in the region. Recreational activities along the river include fishing, rafting, and camping.
