The Plamondon Creek is a tributary of the Plamondon Bay (Gouin Reservoir) located in the western part of the Gouin Reservoir. This stream runs entirely in forest zone in the town of La Tuque, in the administrative region of Mauricie, in Quebec, in Canada.

The Plamondon stream flows successively in the townships of Lacasse and Crémazie. Forestry is the main economic activity of this valley; recreational tourism activities, second.

Secondary forest roads serve both sides of the Plamondon Creek valley. Forest Road R1045 serves the upper and western portions of the Plamondon Creek valley. The R1045 road joins the R2046 road eastwards, which in turn links east to the 202 forest road which runs south to serve the peninsula where the village of Obedjiwan, Quebec is located.

The surface of Plamondon Creek is usually frozen from mid-November to the end of April, however, safe ice circulation is generally from early December to late March.

Plamondon Creek originates at the mouth of an unidentified lake (length: 0.2 kilometres (0.12 mi) altitude: 489 metres (1,604 ft)) surrounded by mountains. The mouth of this head lake is located at:

• 12.4 kilometres (7.7 mi) west of the course of the Pascagama River;
• 7.1 kilometres (4.4 mi) north of the mouth of Plamondon Creek (confluence with Plamondon Bay (Gouin Reservoir);

• 92.9 kilometres (57.7 mi) west of the Gouin Dam erected at the mouth of the Gouin Reservoir (confluence with the Saint-Maurice River).

From the mouth of the head lake, the course of Plamondon Creek flows entirely in forest zone on 16.2 kilometres (10.1 mi) according to the following segments:

• 0.5 kilometres (0.31 mi) to the southeast, including crossing an unidentified lake (length: 0.3 kilometres (0.19 mi); altitude: 484 metres (1,588 ft)), up to at its mouth;

• 8.1 kilometres (5.0 mi) southerly in the township of Lacasse, then Crémazie, first crossing an unidentified lake (length: 7.1 kilometres (4.4 mi); altitude: 402 metres (1,319 ft)) which is connected on the west side to Kamitcickotek Lake, to the mouth of the river.
