Yellowhead Lake is an irregularly shaped lake that is located about 3.7 km southwest of Yellowhead Pass within the boundaries of Mount Robson Provincial Park. It is on the lower reaches of Yellowhead Creek, a large creek that flows into the upper Fraser River above Moose Lake. Yellowhead Lake is a very odd shaped lake. It is about 5.6 km long & its width varies depending on where you are. The lake is fed at its northeast end by Yellowhead Creek, which flows through several swamps above the lake before entering it. About of the way down its southern shore, its only other named tributary, swift-flowing Rockingham Creek enters the lake. Yellowhead Creek exits the lake at its southwestern end & soon reaches the Fraser after passing under the Yellowhead Highway.
