This lake extends in the canton of Poisson and Evanturel. Following the completion of the Gouin Dam in 1948, Mattawa Bay is in its present form as part of the Gouin Reservoir.

Recreotourism activities are the main economic activity of the sector. Forestry comes second.

Some forest roads serve the valleys of the Flapjack River, Bignell Creek and the Mégiscane River. These forest road branches connect to route 404 which serves the Mattawa Bay Valley and connects to the Southeast at route 400 which connects the Gouin Dam to the village of Parent, Quebec via the river valleys Jean-Pierre and Leblanc.

The surface of Mattawa Bay is usually frozen from mid-November to the end of April, but safe ice circulation is generally from early December to the end of March.

Mattawa Bay is separated from Saraana Bay (located to the east) by a peninsula advancing northward on 13.3 kilometres (8.3 mi). This peninsula includes the "Mont de la Tête au Brochet" (English: Mount of the Pike Head) (elevation: 453 metres (1,486 ft)) on the east bank of a strait connecting the northern part of Mattawa Bay with its southern part.

Mattawa Bay is separated from Adolphe-Poisson Bay (located to the west and northwest) by a peninsula advancing northward on 11.7 kilometres (7.3 mi) and an island (length: 5.6 kilometres (3.5 mi)). The latter island blocks the mouth of the Hanotaux Bay (south side of the mouth) and the mouth of Mattawa Bay (west side of the mouth). Another island (length: 2.2 kilometres (1.4 mi)) straddles the eastern side of the mouth of Mattawa Bay.

With a length of 17.0 kilometres (10.6 mi), Mattawa Bay has many islands. This bay is fed on the south side by the Flapjack River.

The mouth of Mattawa Bay converges to the northeast with a larger bay attached to Male Lake. From the mouth of Mattawa Bay, the current flows over 116.9 kilometres (72.6 mi) to Gouin Dam, according to the following segments:

From this dam, the current flows along the Saint-Maurice River to Trois-Rivières.
