Prelude Lake is a stunning subarctic lake stretching approximately 16 kilometers east to west in the Northwest Territories of Canada, situated about 34 kilometers from Yellowknife along NWT Highway 4, the Ingraham Trail. Part of the Cameron River system, the lake features several islands, sheltered coves, and varied shoreline structure that create excellent habitat for multiple fish species. As the centerpiece of Prelude Lake Territorial Park — the largest developed park on the Ingraham Trail — it draws a steady stream of anglers from Yellowknife and beyond, making it one of the more accessible yet productive northern fisheries in the region. The lake's clear subarctic waters, combined with a well-maintained boat launch, dock, and camping facilities, make it an ideal destination for anglers of all experience levels looking to pursue trophy-caliber northern species in a spectacular wilderness setting.
