Plamondon Bay is a freshwater body situated in the western part of Gouin Reservoir, within the territory of the town of La Tuque, in the administrative region of Mauricie, Quebec, Canada.

The hydrographic terrain of Plamondon Bay is accessible via the R1045 forest road originating from Obedjiwan village, Quebec, and passing along the northwest perimeter of Gouin Reservoir.

These two roads intersect approximately 9.1 kilometres (5.7 mi) northwest of the mouth of Plamondon Creek.

Typically, the surface of Plamondon Bay freezes from mid-November until the end of April.

However, secure ice circulation generally takes place from early December to the conclusion of March.
