The Thompson River, the largest tributary of the Fraser River, flows through south-central British Columbia. Renowned for its diverse fish species and scenic beauty, it offers year-round fly fishing opportunities for both beginners and seasoned anglers. The river's varied sections provide habitats ranging from calm stretches to challenging rapids, catering to different fishing preferences.
The Thompson River comprises two main branches: the North and South Thompson Rivers, converging at Kamloops. The North Thompson originates from the Cariboo Mountains, flowing southward, while the South Thompson begins at Little Shuswap Lake. Post-confluence, the river flows westward through Kamloops Lake, then southwest through canyons before joining the Fraser River at Lytton. Each section offers unique fishing experiences, from tranquil lake-fed stretches to dynamic canyon waters.
The Thompson River is home to a variety of fish species, including rainbow trout, steelhead, and several Pacific salmon species such as chinook, coho, sockeye, and pink salmon. The river also supports mountain whitefish and Dolly Varden. Notably, the Adams River, a tributary of the Thompson, hosts one of the world's largest sockeye salmon runs.
Rainbow trout and steelhead in the Thompson River primarily feed on aquatic insects like mayflies, caddisflies, and stoneflies. During salmon spawning seasons, they also consume salmon eggs. Understanding these dietary habits is crucial for selecting effective fly patterns and fishing techniques.
Fly fishing on the Thompson River varies by season and target species. During summer, dry fly fishing is effective for rainbow trout, with patterns like the "California Blonde" being popular. In the fall, steelhead fishing becomes prominent, often using wet flies and sink-tip lines to reach deeper waters. Nymphing with patterns such as the Pheasant Tail Nymph can be productive year-round.
Notable fishing locations along the Thompson River include the stretch from Kamloops Lake to Spences Bridge, known for its rainbow trout and salmon fishing. The area between Spences Bridge and Lytton is renowned for steelhead fishing, especially during the fall. Provincial parks like Juniper Beach and Goldpan offer accessible fishing spots with camping facilities.
Access to the Thompson River is facilitated by several provincial parks and towns along its course. Juniper Beach Provincial Park, located between Cache Creek and Kamloops, provides river access and camping facilities. The towns of Ashcroft and Spences Bridge also offer access points, with nearby accommodations and amenities. Some areas have steep terrain, so caution is advised when accessing the riverbanks.
For rainbow trout, a 5 or 6-weight fly rod with a floating line is suitable. For steelhead, especially in the fall, a 7 or 8-weight rod with a sink-tip line is recommended to reach deeper waters. Waders with felt or studded soles are essential due to the river's slippery and rocky bottom. Polarized sunglasses aid in spotting fish and reducing glare.
The Thompson River's fish populations, particularly steelhead, have faced declines due to various factors. Conservation efforts include catch-and-release practices and habitat protection. Anglers are encouraged to follow regulations, use barbless hooks, and minimize handling of fish to support conservation initiatives.
The Thompson River features varying terrains, including steep canyons and slippery rocks. Anglers should exercise caution when wading, use appropriate footwear, and consider using a wading staff for stability. Weather conditions can change rapidly; carrying a first-aid kit and informing someone of your fishing plans are advisable safety measures.
While the immediate vicinity of the Thompson River may have limited fly shops, nearby towns like Kamloops offer several options. Maricle Consulting and Fly Fishing Adventures in Kamloops provides guided services and local fly fishing expertise. Visiting local shops can provide valuable insights into current river conditions and effective fly patterns.
Several organizations are dedicated to the conservation of the Thompson River and its fish populations. The British Columbia Ministry of Forests, Lands, and Natural Resource Operations implements regulations and conservation initiatives. Anglers are encouraged to support and participate in local conservation efforts to ensure the river's health for future generations.
