Marsh Lake is one of the Yukon's most storied fishing destinations, sitting approximately 35 minutes south of Whitehorse along the Alaska Highway corridor. As the most northerly of the Southern Lakes chain — a 600-kilometre network of interconnected lakes that includes Bennett, Nares, Tagish, Tutshi, and Atlin lakes — Marsh Lake holds the distinction of being the final headwater lake before draining northwest into the Yukon (Lewes) River. Nestled among high mountains and immense boreal forests, this large, glacially carved lake sits within a landscape steeped in Indigenous history and Gold Rush lore, where Tlingit and Southern Tutchone peoples once traded along its shores and Klondike-bound stampeders floated its waters on handmade rafts. The lake's connectivity to the broader Southern Lakes system makes it a dynamic fishery, with fish migrating between lakes and seasonal pulses of salmon passing through on their way to upstream spawning grounds.
