Lake Pahkitew is the lake surrounding Pahkitew Island and serves as a replacement to Lake Wawanakwa after the destruction of Camp Wawanakwa. It is located somewhere in Saskatchewan.

Total Drama: Pahkitew Island

The lake debuts in So, Uh This Is My Team?. While falling from the crashing zeppelin, only half of the contestants' packs contain parachutes. Some of the ones that don't, including Chef Hatchet, land safely in the lake.

In I Love You, Grease Pig!, after the grease pig Shawn is holding bites his head, Shawn runs frantically and falls off a cliff into the lake.

The only time the lake is used in a challenge is in A Blast from the Past. Earlier in the episode, a creature covered in vegetation is seen emerging from the lake. Shawn mistakes it for a zombie and immediately flees the area, and avoids going to the lake, thus missing most of the challenge. For the challenge, both teams are required to cross the dock one member at a time to obtain six dueling sticks. They then must travel back to the other side while trying to knock opposing competitors into the water. To make things harder, Scuba Bear swims beneath the surface the whole time, ready to strike at Chris' command. Near the end of the challenge, the creature, who turns out to be Amy, springs from the lake to confront her sister, who tricked her into getting eliminated two episodes ago.

In Mo Monkey Mo Problems, Chris sends Chef after the eliminated Ella during her farewell musical number. Her bird friends pick her up before he can get to her, and Chef falls off the cliff and into the lake.

In Scarlett Fever, Jasmine and Shawn dived into the lake and found an entrance to the island's interior. Later, Sasquatchanakwa can be seen floating on the lake after being frozen in an ice block as a result of the island going haywire.
