River system Fraser River

The North Thompson River is the northern branch of the Thompson River, the largest tributary of the Fraser River, in the Canadian province of British Columbia. It originates at the toe of the Thompson Glacier [2] in the Premier Range of the Cariboo Mountains, west of the community of Valemount. The river flows generally south through the Shuswap Highland towards Kamloops where it joins the South Thompson River to form the main stem Thompson River.

Contents

For most of its length, the river is paralleled by Highway 5, and the Canadian National Railway (both of which cross the river a couple of times). The North Thompson passes by several small communities, the most notable being Blue River, Clearwater, and Barriere.

Tributaries of the North Thompson River include Canvas Creek, [7] the Albreda River, [8] Thunder River, [9] Mud Creek, [10] Blue River, [11] Mad River, [12] Raft River, [13] Clearwater River, [14] and Barrière River. [15]

The North Thompson's largest tributary is the Clearwater River, which joins at the town of Clearwater. The Clearwater River drains much of Wells Gray Provincial Park.

A notable feature along the North Thompson is Little Hells Gate, a mini-replica of the much larger Hells Gate rapids on the Fraser River. About 17.4 kilometres (10.8 mi) upstream from the small town of Avola, the North Thompson River is forced through a narrow chute only about 30 feet (9.1 m) wide, creating a rapid that resembles the Fraser's famous rapid. Many river rafting companies offer a variety of trips through the rapids.

Thompson River River in British Columbia, Canada

The Thompson River is the largest tributary of the Fraser River, flowing through the south-central portion of British Columbia, Canada. The Thompson River has two main branches, the South Thompson River and the North Thompson River. The river is home to several varieties of Pacific salmon and trout. The area's geological history was heavily influenced by glaciation, and the several large glacial lakes have filled the river valley over the last 12,000 years. Archaeological evidence shows human habitation in the watershed dating back at least 8,300 years. The Thompson was named by Fraser River explorer, Simon Fraser, in honour of his friend, Columbia Basin explorer David Thompson. Recreational use of the river includes whitewater rafting and angling.
